I have a nortel Router in one site runing LLC, IP and ospf. I need to put a cisco at the other end of the Wan link. I have verfied that the T1 is good by having 2 Cisco's at each end and 2 nortel routers on the ckt. when i mix the rotuers i have can not get the circuirt up and running. I have configured both ends with IP and the proper subnet.
IP 184.108.40.206 255.255.255.252
I am not sure where to go from here.
