I have two buildings that are connected together by a multimode fiber. At each building there is a Cisco 1841 router that connects to HQ site via a PTP T1 circuit. Also at each building there is a Cisco 3750 48 port switch for LAN connectivity. I would like to configure a failover configuration, so if one router fails in either building, the building with the failed router can route traffic to the other building. Each building has their own subnet range.
I have this problem too.
