Module Interface IIGMP

Package: inet.networklayer.ipv4
File: src/inet/networklayer/ipv4/IIGMP.ned

Module interface for IGMP modules.

An IGMP module sends notifications about multicast group memberships in hosts, and processes these notifications in multicast routers.

Currently there are 3 versions specified in RFC 1112 (IGMPv1), RFC 2236 (IGMPv2), and RFC 3376 (IGMPv3).

IGMP packets are transported by the IP layer connected to the ipIn/ipOut gates. Some multicast routing protocols (e.g. DVMRP) also communitacate with IGMP messages. They must be connected to the routerIn/routerOut gates, the IGMP module will pass up the unrecognized IGMP packets.
