EVPN

  • EVPN-VXLAN fabric with an IPv6 underlay (QFX5130-32CD and QFX5700)—Starting in Junos OS Evolved Release 22.3R1, you can configure an EVPN-VXLAN fabric with an IPv6 underlay. We support this feature with all service types in MAC-VRF routing instances. You can configure either an IPv4 or an IPv6 underlay across the EVPN instances in the fabric. You can’t mix IPv4 and IPv6 underlays in the same fabric.

    To enable this feature, configure the underlay VXLAN tunnel endpoint (VTEP) source interface in the MAC-VRF instance as an IPv6 address. Also assign IPv6 addresses on the EVPN core-facing interfaces so the devices can reach each other using IPv6. However, you must use the IPv4 loopback address as the router ID for BGP handshaking to work.
