  • Optimized intersubnet multicast (OISM) with MAC-VRF instances and IGMPv2 or IGMPv3 in an EVPN-VXLAN fabric (EX4650, QFX5110, QFX5120, QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 22.2R1, you can configure OISM on leaf devices and border leaf devices in an EVPN-VXLAN ERB overlay fabric with:

    • MAC-VRF routing instances or the default switch instance with IGMPv2 or IGMPv3.

    • IGMP snooping and selective multicast Ethernet tag (SMET) forwarding optimizations with IGMPv2 or IGMPv3.

    When you configure OISM, you must enable OISM and IGMP snooping on all the server leaf and border leaf devices in the EVPN-VXLAN fabric. With a MAC-VRF instance configuration, you configure the OISM supplemental bridge domain (SBD) and all revenue VLANs in the MAC-VRF instances on all leaf and border leaf devices in the fabric.
