  • Symmetric Type 2 EVPN-VXLAN to EVPN-VXLAN DCI stitching (EX4650 and QFX10002)—Starting in Junos OS Release 23.2R1, we support Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) to EVPN-VXLAN symmetric Type 2 route stitching between data center networks using Data Center Interconnect (DCI). Your network can more efficiently interoperate with data center networks that include devices from other vendors who support symmetric Type 2 route stitching. Symmetric Type 2 route stitching means that the VXLAN tunnel endpoint (VTEP) interfaces perform routing and bridging on both the ingress and egress sides of the VXLAN tunnel.

    [See Symmetric Integrated Routing and Bridging with EVPN Type 2 Routes in EVPN-VXLAN Fabrics.]

  • GBP tag propagation with EVPN-VXLAN to EVPN-VXLAN stitching (EX4650 and QFX10002)—Starting in Junos OS Release 23.2R1, we support group-based policy (GBP) tag propagation for EVPN Type 2 and Type 5 routes in a stitched EVPN-VXLAN data center environment. GBP uses existing Layer 3 VXLAN network identifiers (VNIs) in conjunction with firewall filter policies to provide microsegmentation at the device or tag level, independent of the underlying network topology.

    [See Example: Micro and Macro Segmentation using Group Based Policy in a VXLAN.]

  • Domain path attribute for EVPN-VXLAN Type 5 stitching (QFX10002)—Starting in Junos OS Release 23.2R1, we support domain path with EVPN Type 5 routes. Domain path is a BGP attribute used along with EVPN Type 5 routes to identify domains through which routes have already passed.

  • EZ-LAG simplified configuration for ESI LAGs with EVPN dual-homing (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, EX4300-MP, 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 23.2R1, we support a new CLI statement hierarchy level, [edit services evpn]. Using statements at this hierarchy level, you can specify the device attributes and other parameters to configure an Ethernet segment in an EVPN fabric. This new configuration feature, which we call EZ-LAG, simplifies setting up EVPN fabrics with Ethernet segment identifier (ESI) link aggregation groups (LAGs) for dual-homing peer provider edge (PE) devices.

    When you commit a configuration at this hierarchy level, the device automatically invokes a commit script to create a corresponding configuration on the device. You must specify some mandatory elements. You can also include optional elements. For optional elements that you don't specify, the configuration script derives the optional elements (or the script uses default parameters).

    The resulting configuration includes the applicable configuration stanzas corresponding to the different elements you specify at the [edit services evpn] hierarchy level.

    The new hierarchy includes options to override some default parameters, and you can override the commit script settings by manually configuring the related statements.
