Specifying the IP address for local end of TCP connection with peer


[no] neighbor ipv4-addr updated-source ipv4-addr

Specifies the IP address to be used on the local end of the TCP connection with the peer. This is the address of a broadcast, NBMA or loopback interface and the local address of a point-to-point interface. For external peers, the local address must be on an interface that is shared with the peer or with the peer’s gateway when a gateway is used. A session with an external peer will be opened only when an interface with the appropriate local address (through which the peer or gateway address is directly reachable) is operating. For internal peers, a peer session will be maintained when any interface with the specified local address is operating. In any case, an incoming connection will be recognized as a match for a configured peer only if it is addressed to the configured local address.
