Description
Statically configure the interface as an IGMP snooping or MLD snooping multicast router (mrouter) interface—an interface that faces a multicast router or other IGMP or MLD querier, or an interface that acts as a bridge interface toward other multicast routing devices.
If the specified interface is a trunk port, the interface becomes a multicast routing device interface for all VLANs configured on the trunk port. In addition, all unregistered multicast packets, whether they are IPv4 or IPv6 packets, are forwarded to the multicast routing device interface. This unregistered multicast packet forwarding happens even if the interface is configured as a multicast routing device interface only for IGMP snooping or MLD snooping.
In EVPN-VXLAN networks configured to exchange multicast traffic with external
receivers, supported platforms automatically synchronize mrouter port status
by default among peer border leaf devices connected to the external PIM domain. On
those devices, you don't need to explicitly configure the mrouter ports using this
multicast-router-interface statement. See Multicast Router Port Status Synchronization in EVPN-VXLAN Bridged Overlays for details on
the mrouter port status synchronization feature, and Feature Explorer for the platforms that
support that feature.
Default
Disabled. If this statement is disabled, the interface drops IGMP messages it receives.
The interface can either be a host-side or multicast-routing device interface.
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 8.5 for IGMP snooping.
Statement introduced in Junos OS Release 12.1 for MLD snooping.
