5 Verify the configuration
Carry out the display bgp peer command to view the BGP peering relationships
between the routers. If the command gives no output information, a BGP peering
relationship has not been established between the routers.
When the multicast source (Source 1) in PIM-SM 1 sends multicast information,
receivers in PIM-SM 2 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 routers. For example:
# View the brief MSDP peer information on Router C.
[RouterC] display msdp brief
