TEST CONNECTIVITY OF FRAME RELAY ROUTER

FR#sho frame route

TESTING CONNECTIVITY ROUTER 1

R1#ping 192.168.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/36
ms

R1#ping 192.168.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

Frame Relay Monitoring

Router# show interface or show interface serial are the most common commands which show a wide variety of information including showing you the DLCI used for LMI. When monitoring Frame Relay information on the router, a number of items are typically monitored including DLCI and LMI.
Router# debug frame-relay LMI command that you would use to monitor LMI information
Frame Relay Troubleshooting
If a Frame-Relay DLCI attains a state other than “active” meaning inactive or deleted, you can check the Frame-Relay configuration to make sure its configuration matches the configuration of the router acting as the Frame-Relay DTE device.
Router# show frame-relay pvc - can be used to verify that the Frame-Relay PVCs are active and operational
Router# show frame-relay route - can be used to get a listing of the status of all the PVC’s
Router# show frame-relay map - can be used to verify that inverse ARP has successfully mapped remote network layer addresses to the appropriate DLCI.
