Interface Grouping supports multiple clients to PVC and bridging groups, each group will perform
as an independent network, if any other information not in compliance with the criteria will be
forwarded to Data Interface. To support this feature, you must create mapping groups with
appropriate LAN Criteria and WAN interfaces.

5. Configure IGMP function
IGMP, Internet Group Management Protocol, is a communication protocol used to manage the
membership of Internet Protocol multicast groups. IGMP is used by IP hosts and adjacent
multicast routers to establish multicast group memberships. It can be used for online streaming
video and gaming, and allows more efficient use of resources when supporting these uses.
IGMP Snooping is the process of listening to IGMP traffic. IGMP snooping, as implied by the name,
is a feature that allows the Gateway to "listen in" on the IGMP conversation between hosts and
routers by processing the layer 3 packets IGMP packets sent in a multicast network.
When IGMP snooping is enabled in a Gateway it analyses all the IGMP packets between hosts
connected to the Gateway and multicast routers in the network. When a Gateway hears an IGMP
report from a host for a given multicast group, the Gateway adds the host's port number to the
