address-family ipv4 multicast
By default, the BGP IPv4 multicast
address family is not created.
7. Enable the router to exchange
IPv4 unicast routing
information used for RPF check
with peers in the specified peer
group.
peer group-name enable
By default, the router cannot
exchange IPv4 unicast routing
information used for RPF check
with the peers.

By default, the router cannot
exchange IPv6 unicast routing

Specifying the source address of TCP connections
By default, BGP uses the primary IP/IPv6 address of the output interface in the optimal route to a peer or
peer group as the source address of TCP connections to the peer or peer group. You can change the
source address in the following scenarios:
• If the peer's IP/IPv6 address belongs to an interface indirectly connected to the local router, you
must specify that interface as the source interface for TCP connections on the peer. For example,
interface A on the local end is directly connected to interface B on the peer. If you use the peer
x.x.x.x as-number as-number command and x.x.x.x is not the IP address of interface B on the local
end, you must use the peer connect-interface command on the peer to specify the interface whose
IP address is x.x.x.x as the source interface.
