Swapped 2501 with a 2621 router, but Frame Relay went crawling?!
Just replaced the 2501 router with 1 2621 router for a customer. They are running a frame-relay circuit 256k. All we did is configure the same exact configuration on the 2501 to the 2621. After it went online, the connection was extremeley slow. We can telnet to the 2621 router, but barely can do anything to it. Finally, replaced the old 2501 in its place, and the circuit was ot its normal speed. The only thing different between the two routers is the Serial cable, which the 2621 uses the Fast Serial small type. Can a bad cable yield a slow connection like this, instead of no connection? Here;s the configs on the Serial port. Any help o rsuggestions would be appreciated. Thanks,

It is always possible that a bad cable can cause a slow connection. It may cause errors on the line. When you do a "show interface s0" command, do you see input errors incrementing? The best indicator of output errors would be if you see an increasing number of status timeouts in the output of the "show fram lmi" command.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
