Overview of IPv6 Across a VXLAN EVPN Fabric
This section provides an example configuration that enables IPv6 in the overlay of a VXLAN EVPN fabric.
The VXLAN encapsulation mechanism encapsulates the IPv6 packets in the overlay as IPv4 UDP packets and uses IPv4 routing to transport the VXLAN encapsulated traffic.
To enable IPv6 across a VXLAN EVPN fabric, the IPv6 address family is included in VRF, BGP, and EVPN. IPv6 routes are initiated in the tenant VRF IPv6 unicast address-family on a VTEP and are advertised in the VXLAN fabric through the L2VPN EVPN address family as EVPN route-type 2 or 5.
These routes are advertised as EVPN routes on the SPINE.
