Cisco RV315W Broadband Wireless VPN Router Administration Guide
Internet Group Management Protocol (IGMP) is a communication protocol used by
hosts and adjacent routers on IP networks to establish multicast group
memberships. IGMP can be used for online streaming video and gaming, and can
allow more efficient use of resources when supporting these types of
applications.
IGMP Proxy enables hosts that are not directly connected to a downstream router
to join a multicast group sourced from an upstream network. IGMP Snooping
constrains IPv4 multicast traffic at Layer 2 by configuring Layer 2 LAN ports
dynamically to forward IPv4 multicast traffic only to those ports that want to
receive it.
To configure IGMP:
Click Networking > IGMP. The IGMP page opens.
Enter the following information:
•
IGMP Version: Choose either IGMP v1 or IGMP v2.
•
IGMP Proxy: Click Enable to enable IGMP Proxy so that the RV315W can
act as a proxy for all IGMP requests and communicate with the IGMP servers
of the ISP, or click Disable to disable it.
•
IGMP Snooping: You can use IGMP Snooping in subnets that receive IGMP
queries from either IGMP or IGMP Snooping querier. Click Enable to enable
IGMP Snooping, or click Disable to disable it.
Click Save to save your settings.
