2.11.3 Example for Associating BFD with VRRP

In this example, by tracking BFD sessions, a VRRP group can use the backup device to take
over network traffic when the active interface or a link goes Down.
Networking Requirements
To improve link reliability, the user gateway is dual-homed to the upper-layer network. VRRP
is configured on the upper-layer gateway to negotiate the primary and backup links and
implement a switchover.
