Frame Relay Switch

barhamgary
Level 1
Level 1

I have a cisco 2610 router (IOS 12.3(15)) that I am trying to configure as a frame relay switch. It has 2 T1 DSU/CSU cards. I am experiencing some difficulty in activating the 2 serial interfaces. I have attached the show run and show frame route outputs. Any help in getting the configuration correct would be greatly appreciated.

Thanks

I have corrected the configuration and my frame relay switch is up and running. The following is the configuration for the frame relay switch.

Also include "show version", you need enterprise IOS for FR switching.

Do not use attachments unless necessary.

Your configuration looks fine, so I don't think this is an IOS related issue (Commands won't be accepted for unsupported features)

The CE on se0/0 should have dlci 122 and the one on se 0/1 should have dlci 221. If it doesn't work, check if Layer 1 is up on both ends, then try "debug frame lmi" on the CE and the switch.
