Configuring IGMP Proxy

Follow the steps given below to configure IGMP Proxy.
1. Configure router PIM globally.
2. Configure an IP address on the interface (physical or virtual routing interface) that will serve as
3. Enable IGMP Proxy on the interface.
Syntax: [no] ip igmp proxy

Displaying IGMP Proxy traffic

Use the show ip igmp traffic command to see traffic for IGMP Proxy.
PowerConnect#show ip igmp traffic

IP multicast protocols and IGMP snooping on the same device

The PowerConnect device supports global Layer 2 IP multicast traffic reduction (IGMP snooping)
and Layer 3 multicast routing (DVMRP or PIM-Sparse or PIM-Dense) together on the same device in
the full Layer 3 software image, as long as the Layer 2 feature configuration is at the VLAN level.
For Layer 2 multicast traffic reduction, IGMP snooping is performed independently within all VLANs
that have the feature configured. Layer 3 multicast routing is performed between the IP interfaces
that are configured for DVMRP/PIM-Sparse/PIM-Dense. A Layer 3 interface could be a physical,
loopback, or VE port configured with an IP address.

IP multicast protocols and IGMP snooping on the same device
IGMP Proxy is only supported in a PIM Dense environment where there are IGMP clients
connected to the Dell PowerConnect device. The Dell PowerConnect device will not send IGMP
reports on an IGMP proxy interface for remote clients connected to a PIM neighbor, as it will not
be aware of groups that the remote clients are interested in.
PowerConnect(config)#router pim
the IGMP proxy for an upstream device by entering commands such as the following.
PowerConnect(config)#int e 1/3
PowerConnect(config-if-e1000-1/3)#ip address 207.95.5.1/24
PowerConnect(config-if-e1000-1/3)#ip igmp proxy
