Configuring Broadband Settings

When information is broadcast on a network, information packets are delivered to all segments on 
the LAN. This degrades network performance. IP multicasting is a method of forwarding information 
to a group of interested receivers.

Internet Group Management Protocol (IGMP) is used to manage IP Multicast sessions. IGMP 
provides a means to automatically control and limit the flow of multicast traffic throughout your 
network with the use of special multicast queriers and hosts.

Steps

1. Navigate to Settings > Broadband > Multicast. The Multicast page appears.

2. Select the IGMP Proxy check box to enable the  feature. When IGMP Proxy is enabled, the 

gateway issues IGMP host messages on behalf of the hosts discovered through standard 
IGMP interfaces. In other words, the gateway acts as a proxy for its hosts.

3. Select the IGMP Snooping check box to enable the feature. When IGMP Snooping is 

enabled, the gateway analyzes all IGMP packets and selectively forwards multicast traffic 
only to those ports where particular IP Multicast streams are accepted.

4. Select the IGMP Query Response Interval check box to enable the feature. When IGMP 

Query Response Interval is enabled, you control the number of IGMP messages allowed on 
the subnet during the specified duration.

5. Click Save.
