membership information by processing the IGMP reports and leave messages, so traffic can beforwarded 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 thes...

multiple devices are configured as queriers, Brocade recommends that only one device (preferably theone with the traffic source) is configured as a querier. The non-queriers always forward multicast data traffic and IGMP messages to router ports whichreceive IGMP queries or PIM hellos. Brocade recom...

On both switch and router software images, IGMP snooping is either *,G based or S,G based. Thehardware can either match the group address only (* G), or both the source and group (S, G) of thedata stream. This is 32-bit IP address matching, not 23-bit multicast MAC address 01-00-5e-xx-xx-xxmatching....

• 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 configuredas a non-querier (passive).

Configuring the IGMP version for individual ports in a VLAN You can specify the IGMP version for individual ports in a VLAN. For example, the following commandsconfigure ports 4, 5, and 6 to use IGMP V3. The other ports either use the IGMP version specified withthe multicast version command, or the ...

Disabling IGMP snooping on a VLAN When IGMP snooping is enabled globally, you can still disable it for a specific VLAN. For example, thefollowing commands cause IGMP snooping to be disabled for VLAN 20. This setting overrides theglobal setting. device(config)#vlan 20 device(config-vlan-20)#multicast...
