    Release Information

    Statement introduced in Junos OS Release 17.4R1.

    Support added in Junos OS Release 18.2R1 for using distributed MLD in conjunction with Multipoint LDP (mLDP) in-band signalling.

    Description

    Enables distributed MLD on the specified interface, which moves MLD processing from the Routing Engine to the Packet Forwarding Engine for increased performance and capacity to scale. MLD must be enabled for the router to receive multicast packets.

    By default, MLD is disabled on the router. MLD is automatically enabled on all broadcast interfaces when you configure Protocol Independent Multicast (PIM) or Distance Vector Multicast Routing Protocol (DVMRP), but if you want to use distributed MLD, you must explicitly enable it.

    Distributed MLD is only available when chassis network-services enhanced-ip is configured.

    When the distributed command is enabled in conjunction with mldp-inband-signalling, (so PIM act as a multicast LDP inband edge router), it supports interconnecting separate PIM domains via a MPLS-based core.

    Required Privilege Level
