I read in a book that you can bundle links. Example: 2 routers are connected directly to each other, each with 2 interfaces, all in the same subnet. Example:
F0/0: 172.18.0.1 /16 ===== F0/0 172.18.0.3 /16
F0/1: 172:18.0.2 /16 ===== F0/1 172.18.0.4 /16
It said you must enable EIGRP first, or it will give you an interface error. I tried this and could not get this to work. If this can be done, can anyone explain to me how to do this? Thanks.
