  • Enhanced OISM in EVPN-VXLAN ERB overlay networks with an IPv6 underlay (EX4100-48MP, EX4100-24MP, EX4100-48P, EX4100-48T, EX4100-24P, EX4100-24T, EX4100-F-48P, EX4100-F-24P, EX4100-F-48T, EX4100-F-24T, EX4100-F-12P, EX4100-F-12T, EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-24X, EX4400-48F, EX4400-48MP, EX4400-48P, EX4400-48T, EX4650, QFX5120-32C, QFX5120-48T, QFX5120-48Y, and QFX5120-48YM)—Starting in Junos OS Release 23.4R2, you can configure enhanced optimized intersubnet multicast (OISM) for IPv4 and IPv6 multicast data traffic with an Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) edge-routed bridging (ERB) overlay network that has an IPv6 underlay. To configure this feature:

    • Set up the EVPN-VXLAN fabric with an IPv6 underlay:

      • You can use either external BGP (EBGP) or OSPFv3 with IPv6 addressing for the IPv6 underlay.

      • Use the inet6 option when you set the VXLAN tunnel endpoint (VTEP) source interface to the device loopback interface in the EVPN instance (EVI):

        content_copy zoom_out_map
        set routing-instances evpn-instance-name vtep-source-interface lo0.0 inet6

    • Configure the enhanced OISM elements for your multicast EVPN-VXLAN environment in the same way you would configure these elements in an EVPN-VXLAN network with an IPv4 underlay.

      You can configure any of the supported platforms as enhanced OISM server leaf devices, and only EX4650 and QFX5120 switches as enhanced OISM border leaf devices.
