Hello,


We have setup ipsec site-to-site vpn between 2 Cisco 1751 routers. is it possible to configure a Backup link for this vpn ? The best would be to do it by ISDN.


The scenario would be If the crypto tunnel is down ISDN is going up


Thanks.

I'm sure it can.


You might want to implement IPsec + GRE on the site-to-site VPN with a dynamic routing protocol to gain routing awareness.


That way you can detect the change in status of the IPSec tunnel, and perhaps use some "floating static routes" to trigger fail over to the ISDN path.
