Users Guide

A tracked route is considered to match an entry in the routing table only if the exact
IPv6 address and prefix length match a table entry. For example, when configured as a
tracked route, 3333:100:200:300:400::/80 does not match routing table entry
3333:100:200:300::/64. If no route-table entry has the exact IPv6 address and prefix
length, the tracked route is considered to be DOWN.
When you configure IPv6 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.
