Should I enable IGMP proxy?

I suggest you keep the IGMP Proxy enabled to not generate additional network traffic, which in turn leads to better productivity and efficiency of your wireless devices. Enabling IGMP Proxying also resolves mirroring issues that are commonly observed in networks.

What is IGMP proxy used for?

IGMP proxy enables the router to issue IGMP host messages on behalf of hosts that the router discovered through standard IGMP interfaces. The router acts as a proxy for its hosts. E Series routers support IGMP proxy versions 2 and 3.

What does enable IGMP mean?

When enabled, IGMP Snooping monitors IGMP communications among devices and optimizes wireless multicast traffic. This definition does not really explain much. However, a simpler way to put it is that IGMP Snooping can be enabled so that your router acts as a mailman or gate for the multicast traffic.

How do I enable IGMP?

To enable Internet Group Management Protocol (IGMP) snooping, use the ip igmp snooping enable command in switch configuration mode. To return to the default, use the no form of this command.

What is IGMP multicast proxy?

The Internet Group Management Protocol (IGMP) is used by hosts and routers on an IP network to create multicast group memberships. IGMP can be used for resources of web and support applications like online streaming for videos and games.

Should multicast be enabled on router?

The benefit of higher multicast rate is to lower the amount of wireless collisions that your wifi data may have. The biggest effect is seen only when you run multiple media streaming devices or services at the same time. First off, the best setting for multicast rate for your router is usually the lowest amount.

How to enable IGMP proxy on the router?

What is multicast IGMP proxy?

Multicast IGMP Proxy. IGMP Proxy allows hosts in a UDLR (Unidirectional Link Routing) topology that are not directly connected to a downstream router to join a multicast group from an upstream router by using a back channel.

What is IGMP proxy and UDL?

To understand IGMP proxy, let’s first look at what a UDL (Unidirectional Link) is. A UDL is a link where traffic only goes one way. Where do we see this?

What is the IP address of the IGMP querier?

R2 will forward IGMP membership reports to the IGMP querier, and as you’ll see in a bit, the IP address of the IGMP querier will be 192.168.1.254. Between R2 and R3, let’s use OSPF so that R3 can reach the RP address (2.2.2.2) and the subnet of our source:
