A METHOD AND NETWORK NODE FOR USE IN LINK LEVEL COMMUNICATION IN A DATA COMMUNICATIONS NETWORK

摘要

A network node is presented which is configured to associate each of a plurality of MAC addresses with an IP address on a network level. The network node is characterized in that it is configured to, upon reception of a link level message comprising a target IP address and destined to multiple network nodes,compare the target IP address with associated MAC/IP addresses on a network level, and to selectively send the received link level message to at least one other network node on a link level based on the network level comparison. A method and a computer program product are also presented.
