problem of wasting bandwidth is even worse when the LAN segment is not shared, for example in
Allowing switches to snoop IGMP packets is a creative effort to solve this problem. The switch uses the information in the IGMP packets as they are being forwarded throughout the network to determine which segments should receive packets directed to the group address.
IGMP Snooping Configuration
Use the IGMP Snooping Configuration screen to configure the parameters for IGMP snooping. These parameters are used to build forwarding lists for multicast traffic.
To configure IGMP snooping:
1. Select Switching > Multicast > IGMP Snooping > IGMP Snooping Configuration.
2.Enable or disable IGMP Snooping on the switch:
•Enable. The switch snoops all IGMP packets it receives to determine which segments should receive packets directed to the group address.
•Disable. The switch does not snoop IGMP packets.
3.Select whether to validate the IGMP IP header.
•Enable. The switch checks the IP header of all IGMP messages for the Router Alert option. If the option is not present, the packet is dropped.
•Disable. The IGMP IP header is not checked for Router Alert option.
