Purpose: This figure illustrates mapping the data-link connection identifier (DLCI) to the network layer address such as IP.
Emphasize: The DLCI is of local significance, therefore, point out that the same DLCI can be used in multiple places in the network. Frame Relay connections are made using PVCs. The circuits are identified by the DLCI assigned by the service provider.
Explain what Inverse ARP is used for. Static mapping can be configured instead of inverse ARP.
