The command that displays Frame Relay IP address to DLCI mappings is indeed the one that allows you to see how the IP addresses are associated with the respective Data Link Connection Identifiers (DLCIs). When configured on a router that uses Frame Relay, this command provides a list of the configured mappings, effectively showing which IP addresses correspond to which DLCIs. This mapping is essential for ensuring proper communication between devices across the Frame Relay network, as it allows the router to correctly send and receive frames to the intended destinations.

The other options serve different purposes in the context of Frame Relay. One option displays information about the status of PVCs (Permanent Virtual Circuits), which includes the state and configuration details but not the specific IP to DLCI mappings. Another command focuses on Frame Relay LMI (Local Management Interface) status, which is related to the management of the Frame Relay connection but does not provide the mapping information. Finally, the debug command provides real-time information about LMI messages but is not used for displaying configured mappings. This reinforces the importance of using the correct command for accessing specific details about Frame Relay configurations.
