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 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. Related Commands • show track ipv6 route - display information about tracked IPv6 routes, including configuration, current state, and clients which track the route. • track ipv6 route reachability - configure object tracking on the reachability of an IPv4 route. track resolution ipv6 route Configure the protocol-specific resolution value used to scale an IPv6 route metric. Syntax track resolution ipv6 route {isis resolution-value | ospf resolution-value} To return to the default setting, use the no track object-id command. Parameters object-id isis resolution-value ospf resolutionvalue Enter the ID number of the tracked object. Use the range to 1 to 500. Enter the resolution used to convert the metric in the routing table for ISIS routes to a scaled metric. Enter the resolution used to convert the metric in the routing table for OSPF routes to a scaled metric. Defaults None Object Tracking 1185
