how to disable an ethernet link if ISDN PRi goes down

Unanswered Question
May 21st, 2007


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).

How can I achive that control?


Best Regards


I have this problem too.

Hi Roberto

Topological diagram representing your network setup would be easy to understand the things in place at present over there and on top of the same it will be easier to suggest the best possible way out ..
