Can a single Frame Relay PVC be assigned different DLCIs on each end of a virtual circuit?
Yes. The term to know is “locally significant,” which means that a particular DLCI is significant only on the link between two frame devices. Think of DLCIs as the speed-dial numbers stored in your cell phone. • What are the three possible states for a Frame Relay PVC? Explain. Answer: Refer to Table 8-2 and Trouble Ticket 4. The three possible states for a PVC are active, inactive, and deleted. • What is the result if one end of the PVC is set to the default Cisco LMI type and the other end is set to ANSI or Q933A? Answer: As long as the Frame Relay switch attached to the local router is configured for the same LMI, the PVC works just fine. Remember that LMI is the signaling between the router and local frame switch, not an end-to-end function. • Can you ping yourself in Frame Relay? Why or why not? Answer: On point-to-point interfaces, yes. On multipoint interfaces, however, Frame Relay is NBMA, and in a hub-and-spoke topology there is no mapping for yourself. Certainly you could put
