Ip Bgp Neighbor Next-Hop-Self - Alcatel-Lucent OmniSwitch 6850-48 Cli Reference Manual

ip bgp neighbor next-hop-self

Sets the BGP peer to use next hop processing behavior. By default, the next-hop processing of BGP
updates is disabled. Using this command to enable next-hop behavior may be useful in non-meshed
networks where BGP peers do not have direct access to other peers.

Usage Guidelines
•
Use the no form of this command to disable next hop processing behavior.
•
In partially meshed networks a 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 this 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.
