Chapter 4 – Configuring VLANs

IGMP

This parameter enables or disables IGMP Snooping on the VLAN in question.

Note:

If IGMP Snooping is not enabled for the VLAN, both IGMP messages and multicast

streams from routers will be forwarded directly to all members of the VLAN. If any one
member of the VLAN joins a multicast group then

all members of the VLAN will

receive the multicast traffic

. For more information on IGMP see Chapter 7 –

Configuring Multicast Filtering.
