static member ports for multicast group 224.1.1.1.
IGMP snooping querier configuration example
Network requirements
•
As shown in
, in a Layer 2–only network environment, two multicast sources Source 1 and
Source 2 send multicast data to multicast groups 224.1.1.1 and 225.1.1.1 respectively, Host A
and Host C are receivers of multicast group 224.1.1.1, and Host B and Host D are receivers of
multicast group 225.1.1.1.
•
All the receivers are running IGMPv2, and all the switches need to run IGMPv2 snooping. Switch
A, which is close to the multicast sources, is chosen as the IGMP snooping querier.
•
To prevent flooding of unknown multicast traffic within the VLAN, configure all the switches to drop
unknown multicast data packets.
•
Because a switch does not enlist a port that has heard an IGMP query with the default source IP
address of 0.0.0.0 as a dynamic router port, configure a non-all-zero IP address as the source IP
address of IGMP queries to ensure normal creation of Layer 2 multicast forwarding entries.
