II. VLL
This is a kind of point-to-point L2VPN service provided on public networks. VLL can
connect two sites with each other as if they are directly connected by cables. However,
it cannot provide switching directly between multiple points at the service provider level.
3.4.2 CE
It is a user device that is directly connected with a service provider's device.
3.4.3 PE
It is an edge router in backbone network connected with CEs. PE is responsible for
VPN service access, it implement packet mapping and forwarding from private
networks to public network tunnels, and vice versa. It has two types: UPE and NPE.
I. UPE
It is a user-facing PE device, a kind of convergence device for users to access the VPN.
II. NPE
It is a core PE device, located at the edge of the VPLS core network. It provides VPLS
transparent transmission service in the core network.

3.4.4 VSI

Through virtual switch instance (VSI) you can map the actually connected links to each
virtual links.
