  • IGMP and MLD snooping version configuration (ACX7100-32C, ACX7100-48L, ACX7509, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 23.4R1, you can configure the version of IGMP or MLD snooping queries for VLANs or bridge domains associated with Layer 2 (L2) multicast. This configuration ensures that end hosts or CPE devices that are not compliant with RFC 4541 and can’t normally respond to snooping queries of a later version are now able to process and respond to those snooping queries.

    To configure the IGMP or MLD snooping version, use the following CLI statements:

    • set protocols igmp-snooping version version
    • set protocols mld-snooping version version
