ISDN Interface - Policy Based Routing

Unanswered Question

Hi all,

I got new problem here when using the PBR with ISDN backup link.

I have 2 routers A & B, A is leased line router and B is ISDN router. The purposed is customers leased line connected to Router A, if leased line failed then their router will dial to router B.

I use PBR to segregate the traffic among customers. So they can't reach each other, they only can reach my internal LAN. HSRP is configured between R-A and R-B LAN and always active in R-A.

If the HSRP active in R-B, then i got problem with this ISDN router.

The ISDN interface is always in up/up state, even no dial in. This caused the traffic always forward to isdn.

How can we make isdn interface protocol down state, up state when incoming call is make.


I have this problem too.
