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.

track resolution ipv6 route
Configure the protocol-specific resolution value used to scale an IPv6 route metric.
Syntax
track resolution ipv6 route {isis

Parameters
object-id

Enter the resolution used to convert the metric in the routing table for ISIS routes to a
scaled metric.

Usage Information
Use this command to configure the protocol-specific resolution value that converts the actual metric of an IPv6
route in the routing table to a scaled metric in the range 0 to 255.
The UP/DOWN state of a tracked IPv6 route is determined by the user-configurable threshold (the
threshold
metric
command) for a route’s metric in the routing table. To provide a common tracking interface for different
clients, route metrics are scaled in the range 0 to 255, where 0 is connected and 255 is inaccessible.
