Usage Guidelines
The
ipv6 neighbor tracking
command enables the tracking of entries in the binding table. Entry reachability
is tested at every interval configured by the optional
retry-interval
keyword (or every 300 seconds, which
is the default retry interval) using the neighbor unreachability detection (NUD) mechanism used for directly
tracking neighbor reachability.
Reachability can also be established indirectly by using Neighbor Discovery Protocol (NDP) inspection up
to the VERIFY_MAX_RETRIES value (the default is 10 seconds). When there is no response, entries are
considered stale and are deleted after the stale lifetime value is reached (the default is 1440 minutes).
When the
ipv6 neighbor tracking
command is disabled, entries are considered stale after the reachable
lifetime value is met (the default is 300 seconds) and deleted after the stale lifetime value is met.
To change the default values of neighbor binding entries in a binding table, use the
ipv6 neighbor binding
command.
