We had one VPN concentrator (3000 ip 170.48.29.xx) in our main datacenter, currently we are establishing a second data center in another city, we will have an ASA (ip 69.87.39.xx) as VPN concentrator for the 2nd data center. All our users (S2s, vpn client) now connect to the main VPN concentrator (ip 170.48.29.6), if possible I would like to use the ASA as the failover VPN concentrator, if the primary one fails, it will take over as the primary without any user (end point) configuration change. Is this possible?
Thanks for your help.
