I didn't see the part about both routers dialing. Configure dialer watch on both then.

IP won't trigger the call if you're running Dialer-watch, so again, it shouldn't matter. EIGRP and OSPF use MC addresses to communicate back and forth (224.0.0.10 and 224.0.0.5 respectively). This is included in IP.

I would include a "dialer-group <list number>" with a "dialer-list <list number> protocol ip permit". I was just pointing out how it does not use this dialer-list traffic to initiate a call.

Danny,
 
Some questions
1) What if both routers can initiate ISDN calls ?
2) Understand that dialer-watch itself is an interesting traffic. But if we don't deny OSPF hello, won't it always kick up the line ? I just want to know if it is a MUST to either remove the dialer-group or deny OSPF/EIGRP hello when using dialer-watch together.

I would say configure Dialer-Watch only on the calling router. Only the calling router needs to have this configured.

As far as the OSPF hello's, it shouldn't matter. Dialer-Watch is watching for the loss of a route. That is the "interesting" traffic, not IP traffic. I have tested dialer-watch with no dialer-group configured on the BRI or Dialer interface. It works fine. Try it.

HTH,
Danny

Hi group,

R1 ---- ISDN ------ R2
 | |
 |----------FR-----------|

Both R1 and R2 can make ISDN calls and the topology is running OSPF. My question is if dialer-watch is used to watch the remote loopback, is it necessary

1) to configure dialer-watch on both routers ?
2) deny ospf hello in the dialer-list for BOTH routers ?
