Verifying the configuration
# Display the BGP peering relationships on Router A.
[RouterA] display bgp peer
No information is output, because no BGP peering relationship has been established between Router A
and Router D, or between Router A and Router G. This means that the unicast topology is not changed.
# Display brief information about MSDP peers on Router A.
[RouterA] display msdp brief
