[c-nsp] Dot1q Interface detect switchport failure

[James Hampton]

Try using a floating static route, basically you have two static
routes, one of them gets a slightly higher administrative distance
than the other. When the first route is not reachable and dropped from
the table, the second one, with the lower A.D. takes over.

I would like to find out if the dot1q interface on a 7600 is capable of detecting an outage on the switchport of the catalyst 3550, as i need fullfill some kind of backup routing using static routing, so that when the FE port on the switch is down, the router is capable of re-routing traffic to a secondary link. BGP is not an option here. My scenario doesn't allow me to connect the FE directly to the router also, due to the network setup.
