  • VXLAN-GBP profiles with enhanced OISM in EVPN-VXLAN fabrics (EX4100-24MP, EX4100-24P, EX4100-24T, EX4100-48MP, EX4100-48P, EX4100-48T, EX4100-F-12P, EX4100-F-12T, EX4100-F-24P, EX4100-F-24T, EX4100-F-48P, EX4100-F-48T, EX4100-H-12MP, EX4100-H-24F, EX4100-H-24F-DC, EX4100-H-24MP, EX4100-H-24MP-DC, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48MXP, EX4400-48P, EX4400-48T, EX4400-48XP, EX4650, QFX5120-32C, QFX5120-48T, and QFX5120-48Y)—We now support running enhanced optimized intersubnet multicast (OISM) in an EVPN-VXLAN network when you configure the vxlan-gbp-mc-profile VXLAN group-based policy (GBP) unified forwarding table (UFT) profile at the [edit chassis forwarding-options] hierarchy level.

    We don’t assign GBP tags to the multicast traffic. Only unicast traffic carries GBP tags in the VXLAN headers.

    You can use enhanced OISM and VXLAN-GBP with:

    • IPv4 underlay connectivity for the EVPN-VXLAN fabric
    • Intra-VLAN (Layer 2 multicast) and inter-VLAN (Layer 3 multicast) traffic
    • IPv4 multicast traffic with IGMP and IGMP snooping
    • IPv6 multicast traffic with MLD and MLD snooping

    Besides configuring this profile, there are no other configuration differences for either feature when you configure them together.
