Frame Relay: Cannot ping Remote Router
Possible Problem
Solution
Encapsulation mismatch has occurred.
1. When connecting Cisco devices with non-Cisco devices, you must use IETF encapsulation on both devices. Check the encapsulation type on the Cisco device with the show frame-relay map exec command.
2. If the Cisco device is not using IETF encapsulation, use the encapsulation frame-relay ietf interface configuration command to configure IETF encapsulation on the Cisco Frame Relay interface.
For information on viewing or changing the configuration of the non-Cisco device, refer to the vendor documentation.
DLCI is inactive or has been deleted.
1. Use the show frame-relay pvc exec command to view the status of the interface’s PVC.
2. If the output shows that the PVC is inactive or deleted, there is a problem along the path to the remote router. Check the remote router, or contact your carrier to check the status of the PVC.
