Head end termination for EVPN VPWS for business services

Ethernet VPN (EVPN) virtual private wire service (VPWS) is supported on pseudowire subscriber logical interface. Prior to this release, pseudowire subscriber logical interface is used with either Layer 2 circuit or Layer 2 VPN for psuedowire headend termination service. EVPN VPWS as a next generation of pseudowire subscriber interface technology brings the benefit of EVPN to point-to-point service by providing fast convergence upon node failure and link failure through its multi-homing feature. As a result, you can use EVPN VPWS on pseudowire subscriber interface for headend termination into different services. You can configure pseudowire subscriber logical interface for EVPN VPWS so that the pseudowire established by EVPN VPWS can be headend terminated into either Layer 3 VPN or BGP VPLS. The headend termination covers single pseudowire termination and redundant (single home or single-active) pseudowire termination into Layer 3 VPN and BGP VPLS.
