(In Hewlett-Pack­ ard’s implementation of IGMP, a multicast router is not necessary as long as a switch is configured to support IGMP with the querier...

    Multimedia Traffic Control with IP Multicast (IGMP) How IGMP Operates in the join request is determined by the requesting application running on the IGMP client.) When a networking device with IGMP enabled receives the join request for a specific group, it forwards any IP multicast traffic it receives for that group through the port on which the join request was received.

  • Page 48: Using The Switch As Querier

    Multimedia Traffic Control with IP Multicast (IGMP) Using the Switch as Querier Using the Switch as Querier The function of the IGMP Querier is to poll other IGMP-enabled devices in an IGMP-enabled VLAN to elicit group membership information. The switch performs this function if there is no other device in the VLAN, such as a multicast router, to act as Querier.

    IP Routing Features Configuring DHCP Relay Server response validation is an option you can specify when configuring Option 82 DHCP for append, replace, or drop operation. (Refer to “Forwarding Policies” on page 5-84.) Enabling validation on the routing switch can enhance protection against DHCP server responses that are either from untrusted sources or are carrying invalid Option 82 information.

  • Page 248: Multinetted Vlans

    IP Routing Features Configuring DHCP Relay Multinetted VLANs On a multinetted VLAN, each interface can form an Option 82 policy boundary within that VLAN if the routing switch is configured to use IP for the remote ID suboption. That is, if the routing switch is configured with IP as the remote ID option and a DHCP client request packet is received on a multinetted VLAN, the IP address used in the Option 82 field will identify the subnet on which the packet was received instead of the IP address for the VLAN.

    IP Routing Features Configuring DHCP Relay [ ip | mac ] This option specifies the remote ID suboption the routing switch will use in Option 82 fields added or appended to DHCP client packets. The choice of type depends on how you want to define DHCP policy areas in the client requests sent to the DHCP server.

  • Page 254: Udp Broadcast Forwarding, Overview

    IP Routing Features UDP Broadcast Forwarding UDP Broadcast Forwarding Overview Some applications rely on client requests sent as limited IP broadcasts addressed to a UDP application port. If a server for the application receives such a broadcast, the server can reply to the client. Since typical router behavior, by default, does not allow broadcast forwarding, a client’s UDP broadcast requests cannot reach a target server on a different subnet unless the router is configured to forward client UDP broadcasts to that server.

    Virtual Router Redundancy Protocol (VRRP) Overview Overview In many networks, edge devices are often configured to send packets to a statically configured default router. If this router becomes unavailable, the devices that use it as their first-hop router become isolated from the network. VRRP uses dynamic failover to ensure the availability of an end node’s default router.

    Virtual Router Redundancy Protocol (VRRP) Terminology Terminology Backup: A router configured in a VR as a Backup to the Owner configured for the same VR. There must be a minimum of one Backup in a VR to support VRRP operation if the Owner fails. Every backup is created with a configurable priority (default: 100) that determines the precedence for becoming the Master of the VR if the Owner or another Backup operating as the Master becomes unavailable.

  • Page 265: General Operation

    Virtual Router Redundancy Protocol (VRRP) General Operation General Operation VRRP supports router redundancy through a prioritized election process among routers configured as members of the same virtual router (VR). On a given VLAN, a VR includes two or more member routers configured with a virtual IP address that is also configured as a real IP address on one of the routers, plus a virtual router MAC address.

    Virtual Router Redundancy Protocol (VRRP) General Operation Virtual Router (VR) A Virtual Router (VR) instance consists of one Owner router and one or more Backup routers belonging to the same network. Any VR instance exists within a specific VLAN, and all members of a given VR must belong to the same subnet.

    Virtual Router Redundancy Protocol (VRRP) General Operation A subnetted VLAN allows multiple, virtual IP addresses. However, if there are 32 or fewer IP addresses in a VLAN interface and you want VRRP support on multiple subnets, then the recommended approach is to configure a separate VR instance for each IP address in the VLAN.
