L2VPN Access to L3VPN Supported by the Switch

L2VPN Access to L3VPN Supported by the Switch

VLL Access to the Public Network or L3VPN

A Virtual Leased Line (VLL) provides MPLS-based L2VPN services and transparently transmits Layer 2 data over the MPLS network. From the perspective of users, the MPLS access network is a Layer 2 switching network that establishes a Layer 2 connection between users and the carrier network. Users can access the public network or the L3VPN on bearer network of carriers through VLL.

VPLS Access to the Public Network or L3VPN

The Virtual Private LAN Service (VPLS) connects multiple Ethernet sites through the Packet Switch Network (PSN) to make them work as one LAN.

Unlike the point-to-point service of L2VPN, VPLS can be used to connect multiple Ethernet sites of a user to the L3VPN on the bearer network or to the public network through the MPLS access network.
