Description
Enable distributed IGMP by moving IGMP processing from the Routing Engine to the Packet Forwarding Engine. Distributed IGMP reduces the join and leave latency of IGMP memberships.
Distributed IGMP is only available when chassis network-services enhanced-ip is configured.
When you enable distributed IGMP, the following interface options are not supported on the Packet Forwarding Engine: oif-map, group-limit, ssm-map,
and static. However, the ssm-map-policy option is supported on distributed IGMP interfaces. The traceoptions and accounting statements
can only be enabled for IGMP operations still performed on the Routing Engine; they are not supported on the Packet Forwarding Engine. The clear
igmp membership command is not supported when distributed IGMP is enabled.
When the distributed command is enabled in conjunction with mldp-inband-signalling,
(so PIM act as a multipoint LDP inband edge router), it supports interconnecting separate PIM domains via a MPLS-based core.
