I need some advice building a redundant router setup for my lab.
I have a pair of Cisco 2811 routers for the front end and a pair of ASA 5520's to act as backend security appliances.
I need to setup the pairs of routers so they can failover to each other and completely remove single point of failure.
I'm using the builtin active/standby failover on the ASA's and HSRP on the 2811's at the moment.
But how do I wire them up, and how do I configure the routing so the devices can survive any single failure?
