Cisco ASA - 2 Site to Site routes needed for failover -Is possible?
3 physical sites. 2 ASA 5510 (routing mode_). 3rd site is in between ASA sites. 2 different connections. Depending on which link goes down, a certain set of Network Lists for Site to Site VPN is needed to place the 3rd site subnets where they belong depending on which link dies. The tunnels all work. Here is my wonder: Can I automate this somehow in my environment (all Cisco 3750/3560/2960) so that I can leave both tunnels in place so that if either link dies, the appropriate tunnel is picked for failover? Running 8.03 code on ASA. Using EIGRP (love that protocol). Anyone have any ideas?
