Usage
Information
When the interface goes down, FTOS withdraws the route. 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.
