  • EVPN-VPWS over SRv6 underlay (MX240, MX480, MX960, MX2008, MX2010, MX2020, MX10003, and MX10008)—Starting in Junos OS Release 22.3R1, you can configure a single-active or an all-active multihomed Ethernet VPN–virtual private wireless service (EVPN-VPWS) network using Segment Routing over IPv6 (SRv6).

    To enable EVPN-VPWS over SRv6, configure the following:

    1. Include the end-dx2-sid statement at the [edit routing-instances instance-name protocols evpn source-packet-routing srv6 locator name] hierarchy level or the [edit routing-instance routing-instance-name protocols evpn interface interface-name] hierarchy level for the evpn-vpws instance type.

    2. Include the enhanced-ip statement at the [edit chassis network-services] hierarchy level.

    3. Enable advertise-srv6-service and accept-srv6-service in the [edit protocols bgp group name family evpn] hierarchy.

  • Fast reroute for egress link protection in EVPN-VXLAN multihoming environments (EX4400-24MP, EX4400-24P, EX4400-24T, EX4400-48F, EX4400-48MP, EX4400-48P, and EX4400-48T)—Starting in Junos OS Release 22.3R1, you can enable fast reroute egress link protection (ELP) on multihoming peer provider edge (PE) devices with EVPN-VXLAN. Remote sources load balance traffic toward a multihomed customer edge (CE) device by distributing portions of the traffic among the multihoming peer PE devices. This feature minimizes load-balanced traffic loss when a peer PE device’s link to the CE device goes down. The PE device creates a backup VXLAN tunnel called an ELP tunnel. The device uses the ELP tunnel to reroute its portion of the load-balanced traffic to another peer PE device. The device redirects load-balanced traffic on the ELP tunnel until the source routing table converges and the source starts sending the traffic only to the other peer PE devices.

  • Overlay and CE-IP ping and traceroute support for EVPN-VXLAN (MX240, MX480, MX960, MX2010, MX2020, and MX10008)—Starting in Junos OS Release 22.3R1, you can perform ping and traceroute operations within an EVPN-VXLAN overlay or to a specific customer edge [CE] device IP address (CE-IP) across an EVPN-VXLAN overlay. Overlay ping and traceroute, and CE-IP ping and traceroute are used for fault detection and isolation in overlay networks.
