Abstract
Router IP port for an IP router of a IP network system, wherein the router IP port comprises: an encapsulating unit for encapsulating IP data packets received from an IP sub-network to generate Ethernet data packets which are forwarded to an Ethernet unit of said IP router; a decapsulating unit for decapsulating Ethernet data packets received from said Ethernet unit to extract IP data packets to be forwarded; an Egress filter unit for filtering the decapsulated IP data packets extracted by said decapsulating unit in response to a match signal which is generated by an Egress comparison unit which compares a hierarchical destination address prefix of said decapsulated IP data packets logically with configuration data stored in a local memory of said router port.
