i have two 2811 with 4 t1s between them. (2 on each). I would like to connect the two f0/1 interfaces on each router to each other so if both t1s go down on one router the packets coming in f0/0 will just route out f0/1 to the other router that still has its t1s up. i have a block of 32 addresses and i can't really subnet them. if i HAAADD to i could but it would mess things up. i wanted to just take another ip address from that range and put it on that router interface. but there would be a route overlap. to get by this could i just add both interfaces to the same bridge group? any other suggestions?
