Usage Information

The bgp fast-external-fallover command appears in the show config command output.

The fast external fallover configuration is applied only after you manually reset all the existing BGP sessions. As a result, after you execute this command, you must also manually execute the clear ip bgp command in order for the configuration to take effect.
