We're opening a remote site that's going to have a Layer3 switch and 2 Cisco 2801 routers. Each router has 2 T1's going to 2 Cisco 2801 routers at the main location. How do I setup the routers at both locations in a failover mode, so that one of the routers acts as a primary and the second router is a backup?
On the other hand, if we do decide to run the routers in a redundant mode, how do I setup the 2 routers in each location, so that all 4 T1's are being utilized?
Is it possible to have Mulitlink PPP for each router so both the T1 can be act as singal T1 logically and then run the HSRP between both router...
for MLPPP take a look:
