I have two IPSEC site-to-site VPN tunnels set up from my ASA 5520.
Tunnel A goes to remote network 10.16.18.0/24.
Tunnel B goes to remote network 10.16.18.0/24 as well albeit through a different route.
I did this for redundancy. i want the traffic to take tunnel B only when A is down. i set up the routes accordingly.
My problem is that it always routes over tunnel A regardless of the route in the routing table. Even when i only have the tunnel B route defined, it takes the tunnel A route. The crypto map settings are over-riding the route statemnts. I am using static routes.
How can I accomplish this? NAT is not optimal since my partner on the other end has hundreds of devices that would need specific NATs. Please help. is there anyway around this issue.
