HI All I have the test setup for E1 connection. I am using NM-2CE1B in 3660 routers. I have connected two routers back to back for this E1 connection. The problem is when i configure the static ip address, i can ping the opposite end. But when i give ip address negotiated, it can not ping to the other end. The ip address is negotiated and assigned. It can ping to its own ip address, but not to the opposite end. When i give trace route to its own ip address, it traces to the opposite end and ends in the own ip address. when i give debug ip packets it gives unroutable. but in traceroute it can reach the opposite end. please can anyone guide me where i am going wrong.
I am attaching the configuration of the two routers. R1------------E1 back to back----------------R2 R1#sh run Building configuration...
