Usage Information
Use this command to create an object that tracks the reachability of an IPv4 route. In order for a route’s
reachability to be tracked, the route must appear as an entry in the routing table.
A tracked IPv4 route is considered to match an entry in the routing table only if the exact IPv4 address and prefix
length match a table entry. For example, when configured as a tracked route, 10.0.0.0/24 does not match the
routing table entry 10.0.0.0/8. If no route-table entry has the exact IPv4 address and prefix length, the status of the
tracked route is considered to be DOWN.
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.
