Page 26: Internet Protocol Version
JUNOSe 11.0.x Multicast Routing Configuration Guide A broadcast address enables a device to send a datagram to all hosts on a subnetwork. A multicast address enables a device to send a datagram to a specified set of hosts, known as a multicast group, in different subnetworks. Multicast IP packets contain a class D address in the Destination Address fields of their headers.

Page 29: Enabling Ip Multicast
Chapter 1: Configuring IPv4 Multicast Enabling IP Multicast In this implementation, IP multicast works on virtual routers (VRs). By default, IP multicast is disabled on a VR. To enable IP multicast on a VR, access the context for a VR, and then issue the ip multicast-routing command. ip multicast-routing Use to enable IP multicast routing on the VR.

JUNOSe 11.0.x Multicast Routing Configuration Guide Example host1(config)#router ospf host1(config-router)#ip route-type multicast There is no no version. See ip route-type. Defining Permanent IP Multicast Forwarding Entries An mroute is a multicast traffic flow (a (Source, Group) entry used for forwarding multicast traffic).
Page 33: Using The Autosense Mechanism
Chapter 1: Configuring IPv4 Multicast NOTE: Even though you can include any of the preceding commands several times in a route map entry, only the last admission-bandwidth command or qos-bandwidth command in the bandwidth map is used. In other words, if you included the set qos-bandwidth command first and then the set qos-bandwidth adaptive command, the bandwidth map uses the set qos-bandwidth adaptive command.
Page 34: Figure 1: Example Of Adaptive Ipv4 Multicast Bandwidth Detection
JUNOSe 11.0.x Multicast Routing Configuration Guide host1(config-route-map)#set admission-bandwidth adaptive host1(config-route-map)#set qos-bandwidth adaptive host1(config-route-map)#end In this example, any stream with an (S,G) that matches the sdtv access list performs adaptive bandwidth detection for admission control and QoS adjustment. A rate measurement mechanism runs on the ingress line card that polls the forwarding controller (FC) to obtain statistics for each mroute.

JUNOSe 11.0.x Multicast Routing Configuration Guide forwarding. This special interface can be on a different physical port or line module from that of the join interface. Using this mapping function, the router can send a single copy of each multicast stream over the special interface and the access nodes are configured to perform any final replication to the subscribers and merge unicast and multicast data flows onto the subscriber interfaces as necessary.
Page 39: Activating Multicast Qos Adjustment Functions
Chapter 1: Configuring IPv4 Multicast NOTE: Ensure that PIM-SM (or any other upstream multicast protocol) is informed of the group (or source-group) interest. Figure 3: Multicast Traffic Receipt Without Forwarding Activating Multicast QoS Adjustment Functions The ip multicast-routing bandwidth-map command activates the specified bandwidth map.
Page 40: Configuring Hardware Multicast Packet Replication
JUNOSe 11.0.x Multicast Routing Configuration Guide Configuring Hardware Multicast Packet Replication You can configure IPv4 multicast to replicate packets to optimized hardware on a logical port instead of using the forwarding controller (FC) on the router. The bandwidth between the line module and the I/O module or IOA on the E Series router is limited.
Page 41: Figure 5: Packet Flow With Hardware Multicast Packet Replication
Chapter 1: Configuring IPv4 Multicast one copy of the packet is transmitted from the line module to the I/O module or IOA. Replication for each of the ports is performed on the I/O module or IOA. Configuring hardware multicast packet replication for high-density Ethernet is useful when you want to provide the same multicast stream out of some or all of the ports, such as for IP television (IPTV).
Page 42: Supported Modules And Encapsulations
JUNOSe 11.0.x Multicast Routing Configuration Guide Each high-density Ethernet module has eight physical ports, numbered 0–7. A logical port is available for the hardware multicast packet replication feature, numbered port 8. JUNOSe tracks the OIFs in an mroute that have been redirected to use the hardware multicast packet replication hardware.
Page 43: Relationship With Oif Mapping
Chapter 1: Configuring IPv4 Multicast Egress IP policy Egress VLAN policy Relationship with OIF Mapping Multicast OIF mapping enables the router to decrease the inefficiencies associated with replicating streams of multicast traffic. Using OIF maps, IGMP joins that the router receives on a subscriber interface can be mapped to a dedicated multicast VLAN.
Page 44 JUNOSe 11.0.x Multicast Routing Configuration Guide When you configure a unique source MAC address for VLANs on port 8, the hardware multicast packet replication hardware stamps the source MAC address on the VLAN, overwriting any MAC address that you configured. For more information, see Configuring Ethernet Interfaces in the JUNOSe Physical Layer Configuration Guide.
Page 45: Configuring Hardware Multicast Packet Replication
Chapter 1: Configuring IPv4 Multicast Configuring Hardware Multicast Packet Replication To configure hardware multicast packet replication: Configure port 8 on a high-density Ethernet module to accept redirected egress multicast traffic. a. Specify the Gigabit Ethernet interface on port 8. b. Create a VLAN major interface. Create a VLAN subinterface.
Page 46: Monitoring Hardware Multicast Packet Replication
JUNOSe 11.0.x Multicast Routing Configuration Guide Use to set the IGMP version (1, 2, or 3) for the interface or specify a passive interface with only multicast-data-forwarding capability (passive). Example host1:boston(config-if)#ip igmp version passive Use the no version to set the version to the default, IGMPv2. See ip igmp version.
Page 47: Ip And Vlan Statistics
Chapter 1: Configuring IPv4 Multicast IP and VLAN Statistics Use the show vlan subinterface command to display statistics for a VLAN interface configured over port 8. For more information, see Monitoring Ethernet Interfaces in the JUNOSe Physical Layer Configuration Guide. Use the show ip interface command to display statistics for an IP interface configured over port 8.
Page 48: Limiting Interface Admission Bandwidth
JUNOSe 11.0.x Multicast Routing Configuration Guide host1(config-if)#ip block-multicast-sources Use the no version to restore the default behavior of creating mroutes on received multicast packets. See ip block-multicast-sources. Limiting Interface Admission Bandwidth Interface-level multicast admission control is performed when an OIF on the interface is added to the mroute for a given (S,G) multicast data stream and the multicast bandwidth map contains a set admission-bandwidth action for that (S,G).
Page 49: Creating Mroute Port Limits
Chapter 1: Configuring IPv4 Multicast If the bandwidth limit is decreased, no currently admitted OIFs are blocked. However, no new OIFs are admitted until the total admitted bandwidth for the interface drops below the new limit. If the bandwidth is increased to the point that the bandwidth limit for an interface is now exceeded, no currently admitted OIFs for the affected mroutes are blocked.
Page 50: Enabling Port Admission Bandwidth Control
JUNOSe 11.0.x Multicast Routing Configuration Guide When enabled, the admission-bandwidth for a particular (S,G) is read from the multicast bandwidth map and recorded in the mroute when the (S,G) mroute is created. If you configure a port limit and the OIF count on the port exceeds that limit, no OIFs on that port are added to mroutes (that is, OIFs are blocked).
Page 51: Oif Port Reevaluation Example
Chapter 1: Configuring IPv4 Multicast Use to configure a limit on the total multicast bandwidth that can be admitted on a port. Use the priority-bandwidth-limit keyword to configure the priority bandwidth admitted on a port. Use the hysteresis keyword to configure the minimum priority bandwidth limit before the system evaluates mroutes and admits any blocked OIFs.
Page 52: Deleting Multicast Forwarding Entries
JUNOSe 11.0.x Multicast Routing Configuration Guide Deleting Multicast Forwarding Entries You can clear one or more forwarding entries from the multicast routing table. However, if you do so, the entries might reappear in the routing table if they are rediscovered. clear ip mroute Use to delete IPv4 multicast forwarding entries.

Page 65: Configuring Igmp
Chapter 2 Configuring IGMP IP hosts use Internet Group Management Protocol (IGMP) in IPv4 to report their multicast group memberships to neighboring routers. Similarly, multicast routers, such as an E Series router, use IGMP to discover which of their hosts belong to multicast groups.
Page 66: Igmp Overview
JUNOSe 11.0.x Multicast Routing Configuration Guide IGMP Overview The IPv4 address scheme assigns class D addresses for IP multicast. IGMP is the protocol that uses these addresses, which can be in the range 224.0.0.0 to 239.255.255.255. The following addresses have specific functions or are unavailable: 224.0.0.0 is reserved you cannot assign it to a group.
Page 67: Group Membership Reports
Chapter 2: Configuring IGMP The purpose of a group membership query is to discover the multicast groups to which a host belongs. IGMPv2 and IGMPv3 group membership queries have a Max Response Time field. This response time is the maximum amount of time that a host can take to reply to a query.

Page 77 Chapter 2: Configuring IGMP IGMPv2 membership reports to an IGMPv3 report, enabling the router to continue as if it had initially received an IGMPv3 report. After the router is joined to these groups, it sends out PIM join messages and continues to enable joining from these groups, as long as it continues to receive IGMPv1 and IGMPv2 membership reports and no change occurs to the SSM mapping for the group.
Page 78: Limiting The Number Of Accepted Igmp Groups
JUNOSe 11.0.x Multicast Routing Configuration Guide Limiting the Number of Accepted IGMP Groups By default, there is no limit on the number of IGMP groups that an IGMP interface can accept.

Page 79: Including And Excluding Traffic
Chapter 2: Configuring IGMP Use to limit the number of IGMP groups that a port can accept. NOTE: This command is deprecated and might be removed completely in a future release. The function provided by this command has been replaced by the updated by limiting bandwidth of multicast streams using the mroute port admission-bandwidth-limit command.
Page 80: Configuring Explicit Host Tracking
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the no version to remove the static designation. See ip igmp static-exclude. ip igmp static-include Use to statically include the IGMP (S,G) membership for a host that is not capable of dynamically signaling group membership. Example host1:boston(config-if)#ip igmp static-include 10.1.1.1 225.1.2.3 Use the no version to remove the static designation.
Page 81 Chapter 2: Configuring IGMP If the host sending the leave message is not the only host receiving traffic for that group or channel, the router removes the host from the list of hosts on that interface, but keeps the interface in the outgoing interface list for the multicast group or channel.
Page 82: Accepting Igmp Reports From Remote Subnetworks
JUNOSe 11.0.x Multicast Routing Configuration Guide host1(config)#ip igmp explicit-tracking Use the no version to disable explicit host tracking on the interface. Use the no version with the disable-if-igmp-v2-detected keyword to revert to the default explicit host tracking behavior. See ip igmp explicit-tracking. Accepting IGMP Reports from Remote Subnetworks By default, IGMP interfaces accept IGMP reports only from associated subnetworks.

Chapter 2: Configuring IGMP Use the off keyword to enable the interface to accept IGMP reports only from hosts on subnetworks associated with this interface. Example host1:boston(config-if)#ip igmp promiscuous on Use the no version to configure an IGMP interface to use the Router Configuration mode setting to determine the subnetworks from which it can accept IGMP reports.

Chapter 2: Configuring IGMP through the exchange of IGMP messages. However, when acting as the proxy, the router performs the host portion of the IGMP task on the upstream interface, as follows: When queried, sends group membership reports to the group. When one of its hosts joins a multicast address group to which none of its other hosts belong, sends unsolicited group membership reports to that group.

Page 101: Configuring Pim For Ipv4 Multicast
Chapter 3 Configuring PIM for IPv4 Multicast The Protocol Independent Multicast (PIM) protocol is a collection of multicast routing protocols that enables multicast routers to identify other multicast routers to receive packets. This chapter describes how to configure PIM for IPv4 on E Series routers; it contains the following sections: Overview on page 80 Platform Considerations on page 86...
Page 102: Overview
JUNOSe 11.0.x Multicast Routing Configuration Guide Overview The IPv4 implementation of PIM supports PIM dense mode, PIM sparse mode, PIM sparse-dense mode, and PIM source-specific multicast (PIM SSM). Figure 8 on page 80 represents how PIM builds a source, group (S,G) entry in a source-rooted tree (SRT).
Page 103: Overriding Prunes
Chapter 3: Configuring PIM for IPv4 Multicast Figure 9 on page 81 illustrates how PIM dense mode works. When a source sends a multicast packet to a first-hop router, the first-hop router multicasts that packet to its neighbors. Those neighbors in turn forward the packet to their neighbors and their hosts that belong to the multicast group.
Page 104: Pim Sparse Mode
JUNOSe 11.0.x Multicast Routing Configuration Guide Figure 10: Detecting Duplication The upstream routers responsible for the duplication send assert messages to determine which router becomes the forwarder. Downstream routers listen to the assert messages to discover which router becomes the forwarder. PIM Sparse Mode This implementation of PIM sparse mode supports the following features: Rendezvous point (RP) routers...
Page 105: Figure 11: Pim Sparse Mode Operation
Chapter 3: Configuring PIM for IPv4 Multicast Figure 11: PIM Sparse Mode Operation In PIM sparse mode, an RP announces a source and establishes paths from the source to members of a multicast group before multicasting any datagrams. RPs transmit join messages to become part of the shared tree that enables distribution of packets to the multicast group.
Page 106: Joining Groups
JUNOSe 11.0.x Multicast Routing Configuration Guide When all designated routers associated with a specific RP router have switched to the SPT, the RP router sends a join/prune message toward the multicast source. When the multicast source receives this message, it stops sending multicast data through the SPT.
Page 107: Pim Sparse-Dense Mode
Chapter 3: Configuring PIM for IPv4 Multicast NOTE: A PIM router can receive group-to-RP mappings from either BSR or auto-RP, but not from both. Because BSR and auto-RP use different mapping algorithms, the mechanisms cannot coexist. NOTE: Static-override is configured using the override switch in the ip pim rp-address command.
Page 108: Platform Considerations
JUNOSe 11.0.x Multicast Routing Configuration Guide Simplified administrative deployment; you need only configure PIM sparse mode on all router interfaces and issue the necessary SSM commands (including specifying IGMPv3 on the receiver local area network). Support for source lists; you can use source lists, supported in IGMPv3, where only specified sources send traffic to the SSM group.

Chapter 3: Configuring PIM for IPv4 Multicast NOTE: IETF drafts are valid for only 6 months from the date of issuance. They must be considered as works in progress. Please refer to the IETF Web site at http://www.ietf.org for the latest drafts. Before You Begin You can configure PIM on IPv4 and IPv6 interfaces.
Page 110: Enabling Pim On An Interface
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the no version to reenable PIM processing. See pim disable. Enabling PIM on an Interface You can enable PIM on an interface in one of the PIM modes (dense, sparse, or sparse-dense) and specify how often the interface sends hello messages to neighbors. You can configure PIM and IGMP on the same interface.
Page 111: Setting A Priority To Determine The Designated Router
Chapter 3: Configuring PIM for IPv4 Multicast Setting a Priority to Determine the Designated Router You can influence whether a particular router is selected as the designated router with the ip pim dr-priority command. A higher priority value increases the likelihood that a router is selected as the designated router, while a lower value decreases the likelihood.
Page 112: Configuring An Rp Router For Pim Sparse Mode And Pim Sparse-Dense Mode
JUNOSe 11.0.x Multicast Routing Configuration Guide Use to set an interval value, in the range 10–210 seconds, at which the router sends the PIM join/prune message; the default value is 60 seconds. Examples In Router Configuration mode: host1(config-if)#ip pim join-prune-interval 150 In Interface Configuration mode: host1(config-subif)#ip pim join-prune-interval 150 Use the no version to restore the default value, 60 seconds.

Page 115: Configuring Bsr And Rp Candidates For Pim Sparse Mode
Chapter 3: Configuring PIM for IPv4 Multicast Configuring BSR and RP Candidates for PIM Sparse Mode When choosing candidate BSRs, select well-connected routers in the core of the network. Typically, candidate BSRs are a subset of the candidate RPs. A single BSR is elected for the domain of candidate BSRs.
Page 116: Migrating To Bsr From Auto-Rp
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the hold-time keyword to specify the amount of time the BSR keeps an RP in its C-RP list if the BSR does not receive a C-RP advertisement message. The default value is 150 seconds. Use the priority keyword to specify a priority field value that the C-RP sends to the BSR in C-RP advertisement messages.
Page 117: Creating Multicast Vpns
Chapter 3: Configuring PIM for IPv4 Multicast Specify a value of 0 (default) to configure PIM to switch to an SPT when a source starts sending multicast messages. Example host1(config)#ip pim spt-threshold 4 Use the no version to restore the default value, 0. See ip pim spt-threshold.

Page 147: Configuring Dvmrp
Chapter 4 Configuring DVMRP E Series routers support Distance Vector Multicast Routing Protocol (DVMRP) on VRs to forward multicast datagrams through a network. DVMRP is an interior gateway protocol that supports operations within an autonomous system, but not between autonomous systems. The multicast backbone of the Internet, MBone, uses DVMRP to forward multicast datagrams.
Page 148: Identifying Neighbors
JUNOSe 11.0.x Multicast Routing Configuration Guide DVMRP is a dense-mode multicasting protocol and therefore uses a broadcast and prune mechanism. The protocol builds a source-rooted tree (SRT) in a similar way to PIM dense mode. DVMRP routers flood datagrams to all interfaces except the one that provides the shortest unicast route to the source.

Chapter 4: Configuring DVMRP Activating DVMRP on an Interface By default, DVMRP is not activated on an interface. Configuring any DVMRP parameter on an interface automatically activates DVMRP on that interface. You can also activate DVMRP on an interface and use the default parameters. ip dvmrp Use to activate DVMRP on an interface.
Page 152: Filtering Dvmrp Reports
JUNOSe 11.0.x Multicast Routing Configuration Guide ip dvmrp route-limit Use to limit the number of routes that the router can advertise on each interface. Example host1:boston(config)#ip dvmrp route-limit 5000 Use the no version to restore the default value, 7000 routes. See ip dvmrp route-limit.
Page 153: Configuring Dvmrp Summary Addresses
Chapter 4: Configuring DVMRP Use the no version to disable a filter. See ip dvmrp accept-filter. Configuring DVMRP Summary Addresses You can configure an interface to advertise a summary address with a known metric rather than a more specific route. DVMRP advertises the summary address if the DVMRP routing table contains a more specific route that matches the address and mask of the summary address.
Page 154: Changing The Metric For A Route
JUNOSe 11.0.x Multicast Routing Configuration Guide Changing the Metric for a Route The metric for DVMRP is hop count. For example, a route with two hops over a slow serial line is preferable to a route with three hops over a faster optical line. The router increases the number of DVMRP routes in incoming reports by a default metric of one and in outgoing reports by a default of 0.
Page 155: Specifying Routes To Be Advertised
Chapter 4: Configuring DVMRP Use the connected keyword to redistribute routes that are established automatically in the RPF table when another multicast routing protocol, such as PIM, is enabled on an interface. Use the route-map keyword to configure the route map to filter imported routes from the source routing protocol to the current routing protocol.
Page 156: Preventing Dynamic Route Distribution
JUNOSe 11.0.x Multicast Routing Configuration Guide host1:boston(config-if)#ip dvmrp announce-filter boston-list Use the no version to enable the interface to advertise all DVMRP routes that it has learned. See ip dvmrp announce-filter. Preventing Dynamic Route Distribution By default, if you make changes to a route map, the router dynamically redistributes the routes in DVMRP.
Page 157: Disabling And Removing Dvmrp
Chapter 4: Configuring DVMRP Use the no version to disable the exchange of DVMRP unicast routes on an interface not owned by DVMRP. See ip dvmrp unicast-routing. Disabling and Removing DVMRP You can disable DVMRP on a VR or an interface without removing the configuration. You can also remove DVMRP from a VR or an interface.
Page 158: Clearing Dvmrp Routes
JUNOSe 11.0.x Multicast Routing Configuration Guide Use to create and enable DVMRP processing on a VR or to access Router Configuration mode. Example host1:boston(config)#router dvmrp Use the no version to remove DVMRP from a VR. See router dvmrp. Clearing DVMRP Routes You can clear one or more routes from the DVMRP routing table.

Chapter 5 Configuring IPv6 Multicast IPv6 multicast enables a device to send packets to a group of hosts rather than to a list of individual hosts. This chapter describes how to configure IPv6 multicast on the E Series router; it contains the following sections: IPv6 Multicast Overview on page 147 Platform Considerations on page 149 References on page 150...
Page 170: Reverse-Path Forwarding
JUNOSe 11.0.x Multicast Routing Configuration Guide A multicast address enables a device to send a datagram to a specified set of hosts, known as a multicast group, in different subnetworks. IPv6 multicast improves network efficiency by allowing a host to transmit a datagram to a targeted group of receivers.
Page 171: Multicast Packet Forwarding
Chapter 5: Configuring IPv6 Multicast When operating in dense-mode, routers that have multiple paths to the source of the multicast stream initially receive the same stream on more than one interface. In this case, the routers perform an RPF lookup to identify multicast data streams that are not arriving on the best path and send prune messages to terminate these flows.

JUNOSe 11.0.x Multicast Routing Configuration Guide Permanent mroutes are removed if a topology change occurs that affects the mroute. Permanent mroutes may be removed due to certain protocol actions (for example, PIM sparse mode switching from shared to shortest path tree). Outgoing interface lists of permanent mroutes may change due to protocol actions.
Page 177: Using The Auto-Sense Mechanism
Chapter 5: Configuring IPv6 Multicast Using the Auto-Sense Mechanism Video bandwidth is typically considered to be a constant rate 2 Mbps for standard definition television (SDTV) and 10 Mbps for high definition television (HDTV). However, in reality, and depending on achievable video compression, the bit rate can vary.
Page 178: Table 9: Adaptive Mode Algorithm Values
JUNOSe 11.0.x Multicast Routing Configuration Guide To calculate the measured bandwidth of a stream, the router uses the following equation: R = (N – N ) / 5 Where R = Calculated bandwidth of the stream during each sampling interval = Bytes measured at the start of each sampling period (t seconds) = Bytes measured at the end of each sampling period (t+5 seconds) NOTE: When the mroute is first installed in the FC (at t = 0), R...

Page 181: Multicast Traffic Receipt Without Forwarding
Chapter 5: Configuring IPv6 Multicast Figure 15: Multicast OIF Mapping One disadvantage to using multicast OIF mapping is that the multicast traffic bypasses any QoS treatment that is applied to subscriber interfaces. Configuring QoS adjustment resolves this problem. (See Parameter Definition Attributes for QoS Administrators Overview for additional information about configuring QoS adjustment.) With QoS adjustment configured, when a subscriber requests to receive a multicast stream (or, more appropriately, when an OIF is added to the mroute), the router reduces the...
Page 182: Activating Multicast Qos Adjustment Functions
JUNOSe 11.0.x Multicast Routing Configuration Guide Figure 16: Multicast Traffic Receipt Without Forwarding Activating Multicast QoS Adjustment Functions The ipv6 multicast-routing bandwidth-map command activates the specified bandwidth map. By activating the bandwidth map, this command also activates the multicast QoS adjustment function contained in the bandwidth map. CAUTION: To activate multicast QoS adjustment, you must first create a bandwidth map.
Page 183: Figure 17: Packet Flow Without Hardware Multicast Packet Replication
Chapter 5: Configuring IPv6 Multicast The bandwidth between the line module and the I/O module or IOA on the E Series router is limited. A high-density Ethernet module provides eight physical ports that can consume the bandwidth between the line module and the I/O module or IOA before providing enough traffic to support egress line rate for all of these ports.
Page 184: Figure 18: Packet Flow With Optimized Multicast Packet Replication
JUNOSe 11.0.x Multicast Routing Configuration Guide Reduce the number of packets sent from the FC to the module. Reduce the CPU consumed by the FC processing each elaboration of the packet. You can use the feature to increase the bandwidth of multicast traffic out of each of the Gigabit Ethernet ports.
Page 185: Supported Modules And Encapsulations
Chapter 5: Configuring IPv6 Multicast Each port on the I/O module or IOA displayed in Figure 18 on page 162 has two queues. These queues are further down the egress path than the queues found on the line module and populated by the FC. The low-priority queue is dedicated to packets that are received from the line module queues that are dedicated to the physical ports.
Page 186: Relationship With Oif Mapping
JUNOSe 11.0.x Multicast Routing Configuration Guide Relationship with OIF Mapping Multicast OIF mapping enables the router to decrease the inefficiencies associated with replicating streams of multicast traffic. Using OIF maps, MLD joins that the router receives on a subscriber interface can be mapped to a special interface for forwarding.
Page 187: Configuring Hardware Multicast Packet Replication
Chapter 5: Configuring IPv6 Multicast information, see Configuring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide. The regular multicast implementation utilizes interface stacking that provides a unique IPv6 attachment point for each elaboration of the egress multicast packet. For the hardware multicast packet replication feature, you must attach policies to an interface stack over port 8 that defines the encapsulation of the egress multicast traffic.

Page 190: Mld Statistics
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the show ipv6 interface command to display statistics for an IPv6 interface configured over port 8. For more information, see Monitoring IPv6 in JUNOSe IP, IPv6, and IGP Configuration Guide. Multicast traffic redirected by the hardware multicast packet replication feature is displayed in the statistics for the IPv6 or VLAN interface over port 8, not the original IP or VLAN interface over the physical port.
Page 191: Limiting Interface Admission Bandwidth
Chapter 5: Configuring IPv6 Multicast Limiting Interface Admission Bandwidth Interface-level multicast admission control is performed when an OIF on the interface is added to the mroute for a given (S,G) multicast data stream and the multicast bandwidth map contains a set admission-bandwidth action for that (S,G). When enabled, the admission-bandwidth for a particular (S,G) is read from the multicast bandwidth map and recorded in the mroute when the (S,G) mroute is created.
Page 192: Creating Mroute Port Limits
JUNOSe 11.0.x Multicast Routing Configuration Guide If the bandwidth limit is decreased, no currently admitted OIFs are blocked. However, no new OIFs are admitted until the total admitted bandwidth for the interface drops below the new limit. If the bandwidth is increased to the point that the bandwidth limit for an interface is now exceeded, no currently admitted OIFs for the affected mroutes are blocked.
Page 193: Enabling Port Admission Bandwidth Control
Chapter 5: Configuring IPv6 Multicast When enabled, the admission-bandwidth for a particular (S,G) is read from the multicast bandwidth map and recorded in the mroute when the (S,G) mroute is created. When an IOF is subsequently added to the mroute, the OIF is blocked from forwarding data if the additional bandwidth contributed by the (S,G) would exceed the admission-bandwidth limit for the port on which the interface resides.
Page 194: Deleting Multicast Forwarding Entries
JUNOSe 11.0.x Multicast Routing Configuration Guide NOTE: If the multicast bandwidth map that includes the set admission-bandwidth command is changed, all affected mroutes are reevaluated in the same manner described previously. As an example of this function, if the port has accepted a total bandwidth of 3000000 bps, and you set a limit of 2000000 bps on the port, the router does not disconnect any already connected OIFs but prevents the interfaces from accepting any more groups.

JUNOSe 11.0.x Multicast Routing Configuration Guide The following applies when you configure SSM mapping: When enabled, and either you have not configured a static SSM map or the router cannot find any matching access lists, the router continues to accept (*,G) groups. The PIM SSM range must deny any unacceptable SSM group addresses.
Page 217 Chapter 6: Configuring Multicast Listener Discovery A specific MLD interface If you set limits for both a port and interfaces on that port, the router uses the lower of the two limits when determining how many MLD groups an interface can accept. For example, if you set a limit of 10 groups for the port and 15 groups for each interface, the router allows only 10 groups to be accepted among the interfaces.

If a PIM sparse mode router does not receive information from a neighbor or host within a specific time, known as the hold time, it removes the associated information from its routing tables.
Page 240: Platform Considerations
JUNOSe 11.0.x Multicast Routing Configuration Guide Advantages that an SSM-configured network has over a traditionally configured PIM sparse mode network include the following: No need for shared trees or RP mapping (no RP is required). No need for RP-to-RP source discovery through Multicast Source Discovery Protocol (MSDP).

Chapter 7: Configuring PIM for IPv6 Multicast NOTE: IETF drafts are valid for only 6 months from the date of issuance. They must be considered as works in progress. Please refer to the IETF Web site at for the latest drafts. http://www.ietf.org Before You Begin You can configure multicast on IPv4 and IPv6 interfaces.
Page 242: Enabling Pim On An Interface
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the no version to reenable PIM processing. See pim disable. Enabling PIM on an Interface You can enable PIM on an interface in one of the allowed modes and specify how often the interface sends hello messages to neighbors. You can configure PIM and MLD on the same interface.
Page 243: Configuring The Pim Join/Prune Message Interval
Chapter 7: Configuring PIM for IPv6 Multicast override this global setting on a particular interface, use the ipv6 pim dr-priority command in Interface Configuration mode. NOTE: You cannot configure the designated router priority on PIM DM interfaces. ipv6 pim dr-priority Use to set a priority value, in the range 1–254, by which a router is likely to be selected as the designated router.
Page 244: Configuring An Rp Router For Pim Sparse Mode
JUNOSe 11.0.x Multicast Routing Configuration Guide In Interface Configuration mode: host1(config-subif)#ipv6 pim join-prune-interval 150 Use the no version to restore the default value, 60 seconds. Configuring an RP Router for PIM Sparse Mode When you use the router for PIM sparse mode, some VRs must act as RP routers. If you want to control PIM more tightly, you can configure a static RP router.
Page 245 Chapter 7: Configuring PIM for IPv6 Multicast ipv6 pim bsr-candidate Use to define a router as a BSR candidate. To assign an interface from which the router should send messages, specify an interface type and specifier, such as atm 3/0. For details about interface types and specifiers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
Page 246: Switching To An Spt For Pim Sparse Mode
JUNOSe 11.0.x Multicast Routing Configuration Guide Use the interval keyword to specify an interval (from 1 to 65535 seconds) at which the candidate RP sends advertisement messages to the BSR. The default is 60 seconds. Example host1(config)#ipv6 access-list 1 permit 1001::1 host1(config)#ipv6 access-list 1 permit 1002::1 host1(config)#ipv6 pim rp-candidate loopback 1 group-list 1 Use the no version to stop the router from acting as an RP candidate.
Page 247 Chapter 7: Configuring PIM for IPv6 Multicast On one router, specify the other router to be a remote neighbor, and identify the IP address of the interface on the other router that is used for the connection to this router. host1(config-router):boston#remote-neighbor 1001::1 sparse-mode Specify the location of the local interface whose address is used as the source address for the PIM connection to a remote neighbor.
Page 248: Using Pim Sparse Mode Join Filters
JUNOSe 11.0.x Multicast Routing Configuration Guide host1(config-router-rn)#update-source loopback 5 Use the no version to delete the source address from the connection to the remote neighbor. Configuration Example This example uses the configuration shown in Figure 21 on page 216. Two E Series routers called router Boston and router Chicago are running PIM and are connected by MPLS tunnels.

Chapter 7: Configuring PIM for IPv6 Multicast of service (DOS) attacks where large numbers of joins forwarded to each router on the RPT can result in a PIM state explosion and very high memory consumption. For information about how to create access lists, see Configuring Routing Policy in the JUNOSe IP Services Configuration Guide.

JUNOSe 11.0.x Multicast Routing Configuration Guide Figure 22: Network on Which to Configure PIM SSM RP router 4 Source Receiver To configure PIM SSM: Enable PIM SSM on the E Series router. The IANA SSM range is configured by default. You can modify the SSM address range by using the access list. host1(config)#access-list 15 permit ip any host 239.0.0.2 host1(config)#access-list 15 permit ip any 232.0.0.0 0.225.225.225 host1(config)#ipv6 pim ssm range 15...
Page 251: Configuring The Bfd Protocol For Pim
Chapter 7: Configuring PIM for IPv6 Multicast Use the no version to disable SSM. See ipv6 pim ssm. Configuring the BFD Protocol for PIM The ipv6 pim bfd-liveness-detection command configures the Bidirectional Forwarding Detection (BFD) protocol for PIM. The BFD protocol uses control packets and shorter detection time limits to more rapidly detect failures in a network.
Page 252: Removing Pim
JUNOSe 11.0.x Multicast Routing Configuration Guide You can use the minimum-receive-interval keyword to specify the minimum interval at which the local router must receive BFD control packets from its neighbors. The default value is 300 milliseconds. You can use the minimum-interval keyword to specify the same value for both of those intervals.
Page 253: Monitoring Pim
Chapter 7: Configuring PIM for IPv6 Multicast Use to clear the counters for multicast packet statistics on all interfaces or a specified interface. Specify an interface type and identifier, such as atm 3/0 to clear the counters on that interface. For details about interface types and specifiers, see Interface Types and Specifiers in JUNOSe Command Reference Guide.
Page 254: Monitoring Pim Settings
JUNOSe 11.0.x Multicast Routing Configuration Guide undebug ipv6 pim Use to turn off the display of information previously enabled with the debug ipv6 pim command. Example host1#undebug ipv6 pim events There is no no version. See undebug ipv6 pim. Monitoring PIM Settings You can use the show ipv6 pim commands to display information about PIM settings.
