ODR on ISDN network

elfispa · ‎10-07-2002

Hi,

I need to configure ODR in an hub and spoke ISDN network topology (used for backup). Is it possible to use dialer interfaces with virtual profile and unnumbered addressing on the dialer interfaces for this kind of architecture? Or, does CDP work over ISDN with virtual profile and dialer interfaces with unnumbered addressing? Otherwide, is there a different solution?

Thanks

ODR will work across the ISDN connection. Here's a good link on ODR:

If you're worried about routing updates bringing up the backup link...a simpler solution may be configuring a routing protocol and denying the updates.

access-list 101 deny igrp 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255

access-list 101 permit ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255
