I have two datacenters connected via EIGRP dynamic routing. Branch offices terminating at the datacenters via lease lines.
I would like to backup the lease lines with ipsec vpn on either ASA's 5520 or higher or cisco 2800 routers. Using either EIGRP on the ASA's or static routing with higher Advertised distance, i would like to failover to the ipsec vpn tunnels automatically if any lease line is down. I am planning to have a pairs of ASA's between the datacenters and connect all branch offices to the ASA's via ipsec tunnel.
Has anyone done this before?
Will it be better to use cisco routers instead of ASA's with better through-put. does anyone have a design ?
