Users Guide

When you configure IPv4 route reachability as a tracked object, the UP/DOWN state of
the tracked route is also determined by the entry of the next-hop address in the ARP
cache. A tracked route is considered to be reachable if there is an ARP cache entry for
the route's next-hop address.
If the next-hop address in the ARP cache ages out for a route tracked for its
reachability, an attempt is made to regenerate the ARP cache entry to if the next-hop
address appears before considering the route DOWN.
