Ethernet VPN-Virtual Extensible LANs (EVPN-VXLANs) are supported with MPLS as the transport layer.
At present switches provide Layer 2 and Layer 3 VXLAN gateway functions for bare-metal server (BMS) or Virtual Machines (VMs) connected to it by means of a switch network or top-of-rack through an IRB interface. It also supports inter-DC connectivity via Type-5. The current transport layer support is IP. The feature adds MPLS as a transport for Layer 2 VXLANs with EVPN type-5 gateway functionality only. Layer 3 IRB VXLAN gateways will continue to use IP as the transport layer, even if MPLS is configured.
