  • MLDv1, MLDv2, and MLD snooping with OISM and AR in EVPN-VXLAN fabrics (QFX5130-32CD and QFX5700)—Starting in Junos OS Evolved Release 23.1R1, we support optimized intersubnet multicast (OISM) and assisted replication (AR) with Multicast Listener Discovery (MLD) version 1 (MLDv1), MLD version 2 (MLDv2), and MLD snooping for IPv6 multicast data traffic. You can enable MLD and MLD snooping on these devices in EVPN-VXLAN fabrics when you configure the device as:

    • An OISM server leaf or OISM border leaf device.

    • A standalone AR replicator with OISM.

  • Determine IRB interface state changes based on local and remote connectivity states in EVPN fabrics (ACX7100-32C, ACX7100-48L, PTX10001-36MR, PTX10004, PTX10008, PTX10016, QFX5130-32CD, QFX5220, and QFX5700)—Starting in Junos OS Evolved Release 23.1R1, the provider edge (PE) devices in an EVPN fabric consider the following factors when determining the state (up or down) of an L3 integrated routing and bridging (IRB) interface. These factors apply to an L3 IRB interface that is associated with a bridge domain or a VLAN in an EVPN instance (EVI).

    • Associated local L2 interface states

      To customize the L2 interface name and other parameters that the device uses to compute the IRB interface state, configure the interface-state statement at the [edit interfaces irb unit n] hierarchy level.

    • Remote PE device reachability based on the network isolation state of the bridge domain or the EVI

      The device includes the states of the associated EVPN overlay tunnel interfaces in the network isolation state evaluation.

      To define the parameters that determine when an EVI or a bridge domain is in a network isolation state:

      1. Configure the network-isolation group group-name statement at the [edit protocols] hierarchy level to define a network isolation profile using the available options.

      2. Assign the network isolation group profile to a bridge domain or an EVI using the network-isolation-profile group network-isolation-group-name statement at these hierarchy levels:

        • Bridge domain—[edit bridge-domain bd-name bridge-options]

        • EVI—[edit routing-instance instance-name switch-options]
