Description

Use the pim-to-igmp-proxy statement to have Internet Group Management Protocol (IGMP) forward IPv4 multicast traffic across Protocol Independent Multicast (PIM) sparse mode domains.

Configure the rendezvous point (RP) routing device that resides between a customer edge-facing PIM domain and a core-facing PIM domain to translate PIM join or prune messages into corresponding IGMP report or leave messages. The routing device then transmits the report or leave messages by proxying them to one or two upstream interfaces that you configure on the RP routing device.

On the IGMP upstream interface(s) used to send proxied PIM traffic, set the IP address so it is the lowest IP on the network to ensure that the proxying router is always the IGMP querier.

Note too that you should not enable PIM on the IGMP upstream interface(s).

The pim-to-igmp-proxy statement is not supported for routing instances configured with multicast VPNs.

Required Privilege Level

routing—To view this statement in the configuration.

routing-control—To add this statement to the configuration.

Release Information

Statement introduced in Junos OS Release 9.6.
