permanent (OPTIONAL) Enter the keyword permanent to specify that the route is not to be removed, even if the interface assigned to that route goes down. Note: If you disable the interface with an IPv6 address associated with the keyword permanent, the route disappears from the routing table.

The route is re-installed, by FTOS, when the interface comes back up. When a recursive resolution is "broken," FTOS withdraws the route. The route is re-installed, by FTOS, when the recursive resolution is satisfied. After an IPv6 static route interface is created, if an IP address is not assigned to a peer interface, the peer must be manually pinged to resolve the neighbor information.
