FAQ

Why is the feature applicable only when static routing is used and not BGP ?
When BGP is used and PoP interface goes down, BGP session goes down as well. And layer 2 tunnels move to next best PoP. Special monitoring of interface is not necessary.

Why is it compulsory to configure IPv4 Gateway. How is it applicable for this feature ?
Whether the interface is down is judged by monitoring the activity on pop interface. When no packets are received , gateway’s reachability is checked by sending an ARP packet.
