IGMP Proxy
19
Also note the following limitations:
• IGMP Proxy cannot be enabled on the same interface on which PIM SM, PIM DM, is enabled.
• IGMP Proxy is only supported in a PIM Dense environment where there are IGMP clients
connected to the Dell device. The Dell 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.
Configuring IGMP Proxy
Follow the steps given below to configure IGMP Proxy.
1. Configure router PIM globally.
PowerConnect(config)#router pim
2. Configure an IP address on the interface (physical or virtual routing interface) that will serve as
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
3. Enable IGMP Proxy on the interface.
PowerConnect(config-if-e1000-1/3)#ip igmp proxy
Syntax: [no] ip igmp proxy
Once IGMP Proxy is configured and the PowerConnect B-Series TI24X router receives a query on an
IGMP Proxy interface, the router sends a report in response to the query before the IGMP maximum
response time expires.
