Service Tunnel

Previously users could only create PW Pseudowires when building VPN models which was suitable for VLL and VPLS definition. To support VPRN, Service Tunnels can now be created and assigned to VPNs.

Note: Some vendors like Alcatel/Nokia don’t refer to PW and use Service Tunnels for all transport.
