peer connect-interface
Use peer connect-interface to specify a source interface (IP address/IPv6 address) for establishing TCP
connections to a peer or peer group.
Use undo peer connect-interface to restore the default.
Syntax
peer { group-name | ip-address | ipv6-address } connect-interface interface-type interface-number
undo peer { group-name | ip-address | ipv6-address } connect-interface
Default
BGP uses the output interface (IP address/IPv6 address) of the best route destined for the BGP peer or
peer group as the source interface for establishing a TCP connection to the peer or peer group.

Parameters
group-name: Specifies a peer group by its name, a case-sensitive string of 1 to 47 characters. The peer
group must have been created.
ip-address: Specifies a peer by its IP address. The peer must have been created.
ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created.
interface-type interface-number: Specifies an interface by its type and number.
Usage guidelines
If the peer's IP address/IPv6 address belongs to an interface indirectly connected to the local router,
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. When you execute the peer x.x.x.x
as-number as-number command on the local end to specify the BGP peer, and x.x.x.x is not the IP
address of interface B, 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 for establishing a TCP connection.
