I am trying to migrate a P2P serial interface from a 3640 router to a 3845 router but noticed that interface is down.
The config is shown below.
interface Serial0/1----2811 router
ip address x.x.x.1 255.255.255.252
ip address x.x.x.2 255.255.255.252
. What could be the problem.
Under the sh int s0/1 on the the 3640 hardware shows serial while on the 3845 it shows syncronous.
