EVPN MPLS VPWS (RFC 8214) provides the ability to forward customer traffic to / from a given attachment circuit (AC) without any MAC lookup / learning. The basic advantage of VPWS over an L2 EVPN is the reduced control plane signalling due to not exchanging MAC address information. In contrast to LDP pseudowires, EVPN MPLS VPWS uses BGP for signalling. Port based and VLAN based services are supported.

IP traceroute and path MTU (PMTU) discovery both require that routers send ICMP reply messages to the host that invokes each network function. When the route to the destination host traverses an MPLS label-switched path (LSP), the label switching routers (LSRs) will also need to send ICMP reply messages to the originating host.
