Hi,


I have 10 ipsec tunnel with PIX.

All tunnel start from the HQ, where there is no dynamic routing.


I need some advice (or configuration example) to implement a backup of all these tunnel with ISDN links.


thanks for your help

I understand that you would need the IPSEC traffic to flow through the ISDN link, incase the primary link fails.

Dialer watch, backup interface, demand circuit, and floating static are some of the ways to do it.

The following doc gives you the steps to configure redundancy over ISDN using dialer watch.
