how to disable an ethernet link if ISDN PRi goes down
I have a scenario with 2 NAS, everyone with 1 ISDN PRI. The 2 NAS have weighted static routes (redistributed via OSPF between the 2 NAS and the other routers) to foreign sites reachable via ISDN dial-out. What I want to avoid is the situation where one NAS is fully operational and the other has ISDN down but eth up, so it continues to announce itself as the gateway to some foreign offices (this is possible because routes are static, not releted to the ISDN interface, and are redistributed via OSPF).
