EVPN Layer 3 interconnect

In this scenario, EVPN VXLAN tunnels within the data center are terminated on the WAN edge, as shown in the following figure. In the BGP EVPN control plane, only Type-5 prefix routes are imported from EVPN VXLAN peers and are reoriginated towards EVPN MPLS peers. Similarly, in the other direction, EVPN Type-5 prefix routes are imported from EVPN MPLS peers and are reoriginated towards EVPN VXLAN peers within the data center.
