• EVPN-VXLAN to EVPN-VXLAN seamless stitching for EVPN Type 5 routes (ACX7100-32C, PTX10004, PTX10008, PTX10016, QFX5130-32CD, and QFX5700)—Starting in Junos OS Evolved Release 22.4R1, you can configure EVPN-VXLAN to EVPN-VXLAN seamless stitching with EVPN Type 5 (IP prefix) routes between two interconnected data centers or between two points of delivery (pods) in a data center.

  In the EVPN-VXLAN fabric, border leaf or border spine devices act as interconnection gateways. You enable EVPN Type 5 routes in virtual routing and forwarding (VRF) instances on both sides of the interconnection. For each VRF instance, the server leaf devices in the first data center create VXLAN tunnels for Type 5 routes (with corresponding VXLAN network identifiers [VNIs]) toward their local gateway devices. The gateway devices map those VXLAN tunnels to an interconnection tunnel (with a new route distinguisher [RD], route target, and VNI) toward the second data center. The gateway devices in the second data center re-create the Type 5 VXLAN tunnels using their local RD.

  We support one-to-one mapping of Type 5 VRF instances across the interconnection.

• Interfaces support (ACX7509)— Starting in Junos OS Evolved Release 22.4R1, we support the following features:

  • 50-Gbps speed for ACX7509-FPC-20Y line cards

  • 8x50G DAC, 50G DAC, and 2x100G channelization for ACX7509-FPC-4CD line cards

  • Pic violation alarm is raised if you violate port speed combinations.
