If the router needs to map the VCs to network layer addresses, it sends an Inverse ARP message on each VC. The Inverse ARP message includes the network layer address of the router, so the remote DTE, or router, can also perform the mapping. The Inverse ARP reply allows the router to make the necessary mapping entries in its address-to-DLCI map table. If several network layer protocols are supported on the link, Inverse ARP messages are sent for each one.
