When the multicast source in PIM-SM 1 (Source 1) and the multicast source in PIM-SM 2 (Source 2) send
multicast information, receivers in PIM-SM 1 and PIM-SM 3 can receive the multicast data. You can use
the display msdp brief command to view the brief information of MSDP peering relationships between
the switches. For example:

Anycast RP configuration
Network requirements
• As shown in Figure 64 , the PIM-SM domain has multiple multicast sources and receivers. OSPF runs
within the domain to provide unicast routes.
• Configure the Anycast RP application so that the receiver-side DRs and the source-side DRs can
initiate a join message to their respective RPs that are the topologically nearest to them.
• On Switch B and Switch D, configure the interface Loopback 10 as a C-BSR, and Loopback 20 as
a C-RP.
• The router ID of Switch B is 1.1.1.1, and the router ID of Switch D is 2.2.2.2. Set up an MSDP peering
relationship between Switch B and Switch D.
