Fast external fallover
Fast external fallover terminates EBGP sessions of any directly adjacent peer if the link used to reach the peer goes down. BGP does not
wait for the hold-down timer to expire.
Fast external fallover is enabled by default. To disable or re-enable it, use the [no] fast-external-fallover command. For the
fast-external-fallover command to take eect on an established BGP session, you must reset the session using the clear ip
bgp {* |
peer-ipv4-address | peer-ipv6-address} command.
