Has anyone tried to setup a VPN failover between two networks? Is it possible?
I have a fractional leased T1 line with with two 2500 series Cisco routers spaning that T1. In addition, there are 2 Astaros on both networks routing internet traffic. I would like to have a way to manually establish a VPN Network to Network link if and when that T1 goes down. The VPN is setup and can connect however I ran into problems when testing. Routing got completely funky and I needed to reboot both astaro units (which act as default gateways on both networks) to get certain hosts to route back over the T1.
Thanks.
