I am implementing ASA in failover mode so want your help to setup it. I have two 5525 ASAs ver 8.4(6) both will be connected to core switch.
I am little bit confuse that do i need to take a seperate inetrface for failover on both ASA over which no "nameif" and security level configuration be there. OR i can take same interface for failover as well as with nameif "inside" & security level 100 through which my end user behind ASA could reach to internet.
Thanks a lot for this doc..it is very helpful since i will have direct connectivity using crossover cable between two ASA so can i use /30 subnet mask to assign failover ip and do this IPs need to talk with my inside networks.
Also i will put default route from my core switch so next hop should be active ASA inside IP. But if active ASA fail then would i need to change default route towards secondary ASA.
