+ If the router needs to map the VCs to network layer addresses, it will
+ send 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 will be sent for each.
