Page 1 Implementing Layer-3 Multicast Routing on Cisco IOS XR Software This module describes how to implement Layer 3 multicast routing on Cisco ASR 9000 Series Routers running Cisco IOS XR Software. Multicast routing is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to potentially thousands of corporate recipients and homes.

Page 3 Prerequisites for Implementing Multicast Routing • You must install and activate the multicast pie. • For detailed information about optional PIE installation, see Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide • For MLDP, an MPLS PIE has to be installed.
Page 4 (IPv6) to learn whether members of a group are present on their directly attached subnets. Hosts join multicast groups by sending IGMP or MLD report messages. Many multimedia applications involve multiple participants. Multicast is naturally suitable for this communication paradigm.

Page 5 PIM-BIDIR is designed to be used for many-to-many applications within individual PIM domains. This image shows IGMP and PIM-SM operating in a multicast environment. Figure 1: Multicast Routing Protocols Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide, Release 5.1.x...
Page 6 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.
Page 7: Igmp Versions
IGMP. A router running Cisco IOS XR Software does not automatically detect Version 1 systems. You must use the version command in router IGMP configuration submode to configure the IGMP version.
Page 8 (RPF) information. As the name PIM implies, it functions independently of the unicast protocols being used. PIM relies on the Routing Information Base (RIB) for RPF information. Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide, Release 5.1.x...
Page 9 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 10 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.
Page 11 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 12 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 13 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 16 Multicast VPN (MVPN) provides the ability to dynamically provide multicast support over MPLS networks. MVPN introduces an additional set of protocols and procedures that help enable a provider to support multicast traffic in a VPN.

Page 17 BGP/MPLS VPN. In addition to all the ethernet based line cards, Multicast VPN is also supported on the Cisco ASR 9000 Series SPA Interface Processor-700 card from the Cisco IOS XR Software Release 4.0 onwards. Cisco ASR 9000 Series SPA Interface Processor-700 enables the Cisco ASR 9000 Series Routers to support multiple legacy services (such as TDM and ATM) on a router that is primarily designed for Ethernet networks.
Page 18 VPN sites that span across multiple autonomous systems. This feature was added to MLDP profile that enables Multicast Distribution Trees (MDTs), used for Multicast VPNs (MVPNs), to span multiple autonomous systems. There are two types of MVPN inter-AS deployment scenarios: Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide, Release 5.1.x...

In Cisco IOS XR Software, MVPNv6 can have a separate data mdt group configured, which can be different from MVPNv4. But both MVPNv6 and MVPNv4 must have the same default mdt group configured.

Page 45 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 46 Understanding Interface Configuration Inheritance Multicast-Routing Configuration Submode In Cisco IOS XR software release 3.7.2 and later, basic multicast services start automatically when the multicast PIE (asr9k-mcast-p.pie) is installed, without any explicit configuration required. The following multicast services are started automatically: •...
Page 47 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 48: Multicast Routing Information Base
Understanding Enabling and Disabling Interfaces, on page 48 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.
