Redundant VPN Tunnel if Serial Link down

Hi All,

We have a cisco 1760 Router with 3 interfaces

Lan
Serial1/0 - Leased line to our HQ
Dialer0 - BT Broadband Line

Routing looks like this

route 0.0.0.0 0.0.0.0 dialer0
route 10.0.0.0 0.0.0.255 serial1/0

So all internet traffic goes out the BT Line, and any internal network traffic uses the Leased Line.

Simples so far.

Now, yesterday we had an issue where the leased line was down (virgin media fault). Is it possible for us to setup a backup VPN Tunnel From the dialer0 interface to one of our other HQ routers, so if leased line is down the vpn tunnel comes up.

I couldnt find much information for a cisco noob.

Had a go yesterday, I managed to get the tunnel up (shown as connected and i could see packets going across) but couldnt ping anything equipment on either side.

All is well now by the way, but need to get it implemented sooner rather then later.

Leased line endpoint is a cisco 2600 router, and the vpn endpoint would be a different Cisco PIX 515E....

Cheers,

Ash

Could you post the logs from the UI (obviously with the IP's + connection details scrubbed)? With logging enabled. It will tell us what is happening and maybe point you in the right direction.
