Carry out the display bgp peer command to view the BGP peering relationships
between the switches. If the command gives no output information, a BGP
peering relationship has not been established between the switches.
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:
# View the brief MSDP peer information on Switch B.
[SwitchB] display msdp brief

Anycast RP
Configuration
Network requirements
■ The PIM-SM domain has multiple multicast sources and receivers. OSPF runs
within the domain to provide unicast routes.
■ It is required to 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, while the router ID of Switch D is 2.2.2.2.
Set up an MSDP peering relationship between Switch B and Switch D.
