Page 94: Protocol Independent Multicast
SAFI RIB. Both multicast unicast and unicast databases are outside of the scope of PIM. The Cisco IOS XR implementation of PIM is based on RFC 4601 Protocol Independent Multicast - Sparse Mode (PIM-SM): Protocol Specification. For more information, see RFC 4601 and the Protocol Independent Multicast (PIM): Motivation and Architecture Internet Engineering Task Force (IETF) Internet draft.
Page 95: Pim-Sparse Mode
To run SSM with IGMPv3, SSM must be supported on the multicast router, the host where the application is running, and the application itself. Cisco IOS XR Software allows SSM configuration for an arbitrary subset of the IP multicast address range 224.0.0.0 through 239.255.255.255. When an SSM range is defined, existing IP multicast receiver applications do not receive any traffic when they try to use addresses in the SSM range, unless the application is modified to use explicit (S,G) channel subscription.

PIM-BIDIR. Note In Cisco IOS XR Release 4.2.1, Anycast RP is not supported on PIM Bidirectional mode. PIM-BIDIR is designed to be used for many-to-many applications within individual PIM domains. Multicast groups in bidirectional mode can scale to an arbitrary number of sources without incurring overhead due to the number of sources.

Label Switching Traffic Engineering (MPLS-TE) and IP multicast coexistence is supported in Cisco IOS XR Software by using the mpls traffic-eng multicast-intact IS-IS or OSPF router command. See Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide for information on configuring multicast intact using IS-IS and OSPF commands.
Page 101: Designated Routers
Designated Routers Designated Routers Cisco routers use PIM-SM to forward multicast traffic and follow an election process to select a designated router (DR) when there is more than one router on a LAN segment. The designated router is responsible for sending PIM register and PIM join and prune messages toward the RP to inform it about host group membership.

Page 108: Ipv6 Connectivity Over Mvpn
IPv6 Connectivity over MVPN On the Cisco ASR 9000 Series Routers, in Cisco IOS XR Software starting Release 4.2.1, IPv6 connectivity is supported between customer sites over an IPv4-only core network with a default VRF. VPN PE routers interoperate between the two address families, with control and forwarding actions between IPv4-encapsulated MDTs and IPv6 customer routes.
Page 109: Bgp Requirements
PIM-SSM MDT tunnels cannot be set up without a configured BGP MDT address-family, because you establish the tunnels, using the BGP connector attribute. See the Implementing BGP on Cisco IOS XR Software module of the Cisco ASR 9000 Series Aggregation Services Router Routing Configuration Guide for information on BGP support for Multicast VPN.

Page 199: Multicast Configuration Submodes
Cisco IOS XR Software moves control plane CLI configurations to protocol-specific submodes to provide mechanisms for enabling, disabling, and configuring multicast features on a large number of interfaces. Cisco IOS XR Software allows you to issue most commands available under submodes as one single command string from the global or XR config mode.
Page 200: Igmp Configuration Submode
MSDP configuration submode. Understanding Interface Configuration Inheritance Cisco IOS XR Software allows you to configure commands for a large number of interfaces by applying command configuration within a multicast routing submode that could be inherited by all interfaces. To override the inheritance mechanism, you can enter interface configuration submode and explicitly enter a different command parameter.
Page 201: Understanding Interface Configuration Inheritance Disablement
Understanding Enabling and Disabling Interfaces, on page 187 Understanding Enabling and Disabling Interfaces When the Cisco IOS XR Software multicast routing feature is configured on your router, by default, no interfaces are enabled. To enable multicast routing and protocols on a single interface or multiple interfaces, you must explicitly enable interfaces using the interface command in multicast routing configuration mode.
