Can anyone point me to an example of what we want to acheive.
We have a site to site wireless link that we want to implment a backup solution if the wireless goes down. The idea is to use ADSL site to site VPN over the Internet.
I am stuck for ideas on how to do this and have tried it in a lab but can not get traffic to pass through the tunnel. I have setup site to site before but this is different. Should we be using a routing protocol, or will secondary routes do the trick.
There must be some configs on Cisco's web site but I can not find it.
We have two 1801s with ADSL interfaces in them and the idea was to plug the bridges in to the WAN FE0.
Thanks for looking at this for me. I am really stuck.
I have tried using RIP and then a floating static route.
The senario is that I want to connect two sites with a wireless link and have a back up via VPN over ADSL. I have setup the routers so that fe0 on each router are plugged in to gether as if they had a wireless bridge each. Because I am in a lab and don't have two adsl lines to test I have setup vlans on the switches with a hub in between.
The problem now is that the traffic goes over the the fe 0 links but I still see traffic being decryped by the VPN, but not encryped. This happens after I shut down the fe 0 and it fails over to the VPN. The VPN works fine, but it is not failing back properly. If I shut down vlan7 then it breaks the traffic somehow.
I have attached both configs and also the output from show crypto ipsec sa.
