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 effect on an established BGP session, you must reset the session using the clear ip bgp {* | peer-ipv4-address | peer-ipv6-address} command.
