EVPN

  • Support for EVPN-MPLS (PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 23.1R1, you can configure EVPN-MPLS on PTX Series routers. EVPN-MPLS is a solution that extends Layer 2 VPN services over an MPLS network.

    [See EVPN Overview.]

  • Automatically derived ESI support on EVPN-MPLS (ACX7100-32C, ACX7100-48L, PTX10001-36MR, PTX10004, PTX10008, and PTX10016)—Starting in Junos OS Evolved Release 23.1R1, you can configure multihomed devices in an EVPN-MPLS network to automatically generate the ESI from the:

    • System ID and administrative key on the remote customer edge (CE) device (partner).

    • Locally configured MAC and local discriminator values.

    [See Other Methods to Auto-Derive the ESI.]

  • 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]
