Release Information

Statement introduced in Junos OS Release 17.2R1.

Description

Enable PIM distributed designated-router (DR) functionality on IRB interfaces associated with EVPN virtual LANs (VLANs) that have been configured with IGMP snooping. By effectively disabling certain PIM features that are not required in this scenario, this statement supports using PIM to perform intersubnet, that is, inter-VLAN, multicast routing more efficiently.

When you configure this statement, PIM ignores the DR status of the interface when processing IGMP reports received on the interface. When the interface receives the IGMP report, the provider edge (PE) device sends PIM upstream join messages to pull the multicast stream and forward it to the interface—regardless of the DR status of the interface. The statement also disables the PIM assert mechanism on the interface.
