Correct answer is C: Track both the OMP session and a list of remote prefixes. list-name is the name of a prefix list configured with the policy lists prefix-list command on the vEdge router: vEdge(config-vrrp)# track-prefix-list list-name If all OMP sessions are lost, VRRP failover occurs as described for the track-omp option. In addition, if reachability to all the prefixes in the list is lost, VRRP failover occurs immediately, without waiting for the OMP hold timer to expire, thus minimizing the amount of overlay traffic is dropped while the vEdge routers determine the VRRP master.
