10.2.4 Configuring IGMP VLAN Registration
Purpose
Use these commands to configure IGMP VLAN Registration (IVR) on the device. IVR is designed
for applications using wide-scale deployment of multicast traffic. It eliminates the need to duplicate
multicast traffic for clients in each VLAN. Multicast traffic for all groups is only sent around the
VLAN trunk once — only on the multicast VLAN.
For more information about the use of IGMP VLAN Registration, refer to Section 10.3.1 .
