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. // // @see IGMPv2 // moduleinterface IIGMP { @display("i=block/cogwheel_s"); gates: input ipIn @labels(IPv4ControlInfo/up); output ipOut @labels(IPv4ControlInfo/down); input routerIn @labels(IPv4ControlInfo/up); output routerOut @labels(IPv4ControlInfo/down); }
