Usage
Information
The updates are sent to all the neighbors in the peer-group and all the neighbors will have the same
attributes including next-hop.
Enabling or disabling outbound optimization will dynamically resets all neighbor sessions.
When you enable outbound optimization, all peers receive the same update packets. Also, the next-hop
address, which is chosen as one of the addresses of the neighbor's reachable interface, is the same for
all peers.

Enable next-hop resolution through other routes learned by BGP.

To disable next-hop resolution, use the no bgp recursive-bgp-next-hop command.

Command Modes
ROUTER BGP
Usage
Information
This command is a knob to disable BGP next-hop resolution via BGP learned routes. During the
next-hop resolution, only the first route that the next-hop resolves through is verified for the route’s
protocol source and is checked if the route is learned from BGP or not.
The clear ip bgp command is required for this command to take effect and to keep the BGP database
consistent. Execute the clear ip bgp command right after executing this command.
