Disabling BFD for VRRP

If you disable any or all VRRP sessions, the sessions are torn down.
A final Admin Down control packet is sent to all neighbors and sessions on the remote system change to
the Down state.
To disable all VRRP sessions on an interface, sessions for a particular VRRP group, or for a particular VRRP
session on an interface, use the following commands.
• Disable all VRRP sessions on an interface.
INTERFACE mode
no vrrp bfd all-neighbors
• Disable all VRRP sessions in a VRRP group.
VRRP mode
bfd disable
• Disable a particular VRRP session on an interface.
INTERFACE mode
no vrrp bfd neighbor ip-address
Configuring Protocol Liveness
Protocol liveness is a feature that notifies the BFD manager when a client protocol is disabled.
When you disable a client, all BFD sessions for that protocol are torn down. Neighbors on the remote
system receive an Admin Down control packet and are placed in the Down state.
To enable protocol liveness, use the following command.
• Enable Protocol Liveness.
CONFIGURATION mode
