Queriers and non-queriers membership information by processing the IGMP reports and leave messages, so traffic can be forwarded to ports receiving IGMP reports. An IPv4 multicast address is a destination address in the range of 224.0.0.0 to 239.255.255.255. Addresses of 224.0.0.X are reserved. Because packets destined for these addresses may require VLAN flooding, devices do not snoop in the reserved range. Data packets destined to addresses in the reserved range are flooded to the entire VLAN b

VLAN-specific configuration multiple devices are configured as queriers, Brocade recommends that only one device (preferably the one with the traffic source) is configured as a querier. The non-queriers always forward multicast data traffic and IGMP messages to router ports which receive IGMP queries or PIM hellos. Brocade recommends that you configure the device with the data traffic source (server) as a querier. If a server is attached to a non-querier, the non-querier always forwards traffic

MAC-based forwarding implementation on FastIron X Series devices On both switch and router software images, IGMP snooping is either *,G based or S,G based. The hardware can either match the group address only (* G), or both the source and group (S, G) of the data stream. This is 32-bit IP address matching, not 23-bit multicast MAC address 01-00-5e-xx-xx-xx matching. When any port in a VLAN is configured for IGMP v3, the VLAN matches both source and group (S, G) in hardware switching. If no ports

IGMP snooping configuration • A user can configure static router ports to force all multicast traffic to these specific ports. • If a VLAN has a connection to a PIM-enabled port on another router, the VLAN must be configured as a non-querier (passive). When multiple snooping devices connect together and there is no connection to PIM ports, one device must be configured as a querier (active). If multiple devices are configured as active (queriers), only one will keep sending queries after exchang
