Multicast Open Shortest Path First (MOSPF) or Distance Vector Multicast Routing Protocol (DVMRP). Cisco IOS XR Software supports Protocol Independent Multicast in sparse mode (PIM-SM), Protocol Independent Multicast in Source-Specific Multicast (PIM-SSM), and Protocol Independent Multicast in Bi-directional mode (BIDIR) permitting these modes to operate on your router at the same time.

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 22: Pim-Source Specific Multicast
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.

This type of distribution tree is called a shortest path tree or source tree. By default, the Cisco IOS XR Software switches to a source tree when it receives the first data packet from a source. The following process describes the move from shared tree to source tree in more detail: 1 Receiver joins a group;...
Page 25: Designated Routers
(In OSPFv2, the behavior is slightly different.) 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 37: Multicast Vpn Hub And Spoke Topology
Such a configuration brings natural protection from traffic leakage - from one spoke site to another. Cisco IOS XR Software implementation of hub and spoke follows the one- site-to-one VRF model. Any site can be designated as either a hub or spoke site, based on how the import or export of routes is setup.
Page 38: Label Switched Multicast (Lsm) Multicast Label Distribution Protocol (Mldp) Based Multicast Vpn (Mvpn) Support
If required, interspoke multicast can flow by turning around the traffic at Hub sites. These enhancements are made to the Multicast Hub and Spoke topology in Cisco IOS XR Software Release 4.0: • Auto-RP and BSR are supported across VRFs that are connected through extranet. It is no longer restricted to using static RP only.

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 76: Multicast-Routing 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 77: Understanding Interface Configuration Inheritance Disablement
Understanding Interface Configuration Inheritance Disablement As stated elsewhere, Cisco IOS XR Software allows you to configure multiple interfaces by applying configurations within a multicast routing submode that can be inherited by all interfaces. To override the inheritance feature on specific interfaces or on all interfaces, you can enter the address-family IPv4 or IPv6 submode of multicast routing configuration mode, and enter the interface-inheritance disable command together with the interface type interface-path-id or interface all command.
Page 78: Understanding Enabling And Disabling Interfaces
Understanding Enabling and Disabling Interfaces, on page 68 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.

For detailed information about optional PIE installation, see Cisco IOS XR Getting Started Guide for the Cisco CRS Router. For running AMT, an mcast PIE must be installed. • Ensure that you are in a user group associated with a task group that includes the proper task IDs. The command reference guides include the task IDs required for each command.
