Abstract:
1. A method of updating an inverse ARP table in an IP network over a partially meshed Frame Relay network wherein the Frame Relay network includes at least one hub which is linked to each one of a plurality of spokes by a Permanent Virtual Circuit (PVC), said PVC being identified by a first Data Link Connection Identifier (DLCI) associated with said hub and a second DLCI associated with said spoke, said hub and said set of spokes defining an IP subnet having a subnet address, and each spoke having an inverse ARP table in which said first DLCI identifying a PVC is mapped with the IP address of said hub as entry, said method comprising the steps of: defining said first DLCI being mapped with a default address identifying said hub as the destination for any frame addressed to one or more spokes on said subnet; and automatically entering said default address as an entry into said inverse ARP table.
