neighbor next-hop-self

Use this command to make the router the next hop for a BGP-speaking neighbor or peer group. This command allows a BGP router to change the nexthop information that is sent to the iBGP peer. The nexthop information is set to the IP address of the interface used to communicate with the neighbor.

Use the no parameter with this command to disable this feature.

For unnumbered peer, IPv4 unicast mode commands are configured under v4-unnumbered-mode.
