I have a client that currently has two sites connected via IPSec tunnels running on Cisco ASA 5505 firewalls. They want to add a T1 as a more reliable link between the sites but keep the VPN for failover and the ISP links for Internet traffic. They have two scenerios they want to automatic failover for. First should the T1 fail then traffic should reroute over the VPN. Second should the Internet fail at a single site all Internet traffic should reroute through the T1 and out the other side. If I add 1841-T1 routers to each site for the T1 connection can I use OSPF to accomplish these goals? If not can you suggest another way?
I have this problem too.
