Configuring BFD Support for VRRP Tracking

The steps below show you how to configure and verify BFD support for VRRP protocol, so that VRRP is
a registered protocol with BFD and receives forwarding path detection failure messages from BFD.
1
To associate VRRP protocol with BFD liveliness detection, register VRRP with BFD at the protocol
level using the vrrp bfd-state
-> vrrp bfd-state enable
Note. VRRP protocol supports BFD in the echo-only operational mode.
