Usage Information
Use this command to create an object that tracks the reachability of an IPv6 route.
In order for a route’s reachability to be tracked, the route must appear as an entry
in the routing table.
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
