Configuring MLD

To configure the Multicast Listener Discovery (MLD) protocol, include the mld statement:

mld {accounting;interface interface-name {disable;(accounting | no-accounting);group-policy [ policy-names ];immediate-leave;oif-map [ map-names ];passive;ssm-map ssm-map-name;static {group multicast-group-address {exclude;group-count number;group-increment increment;source ip-address {source-count number;source-increment increment;}}}version version;}maximum-transmit-rate packets-per-second;query-interval seconds;query-last-member-interval seconds;query-response-interval seconds;robust-count number; traceoptions {file filename <files number> <size size> <world-readable | no-world-readable>;flag flag <flag-modifier> <disable>;}}

You can include this statement at the following hierarchy levels:

  • [edit protocols]
  • [edit logical-systems logical-system-name protocols]

For an overview of logical systems and a detailed example of logical system configuration, see the JUNOS Logical Systems Feature Guide.

By default, MLD is automatically enabled on all broadcast interfaces when you configure Protocol Independent Multicast (PIM) or the Distance Vector Multicast Routing Protocol (DVMRP).
