Usage Guidelines
•
Use the no form of this command to disable the next-hop-self parameter.
•
In meshed networks, the BGP peer may not have direct connections to other peers. When such a peer
receives route updates from these distant peers (via other peers), it may treat the remote peer as if it
were the next hop in the routing path. Packet forwarding will not work in such a case because no direct
connection exists. This command allows the peer to deem itself the next hop on the routing path so that
the two non-connected peers can route packets. This peer would have a direct connection to both peers
that want to exchange packets.
•
The BGP peer is restarted after issuing this command.
