I've been reading through this support community for about a week now and found many discussions similar to my question about using fa/0 & fa/1 on my 2811's.
Attached is a drawing of our typical remote locations. Left side is current configuration, right side is what I'm trying to accomplish. Basically one 2811 router and two 3560 switches, and I'm looking for some type of solution that would keep switch2 up should switch1 fail. All Vlans (voice, data, and soon wireless AP) on both switches.
