Service endpoints can be categorized as:
An AC endpoint is a L2 link between a PE device and a CE device. The AC endpoint can be an untagged port, or a tagged port with one or more VLANs. AC endpoints with different VLAN tags can be configured in a single VPLS instance.
A VLL instance interconnects two AC endpoints through a pseudowire, while a VPLS instance forms a full mesh interconnection between multiple AC endpoints through multiple PWs.
The following endpoints are supported:
Both regular port and port-channel interfaces can be used to form port-vlan, untagged port-vlan, and port-vlan-vlan endpoints.
VPLS service endpoints are represented by logical interfaces (LIFs). By using LIFs, features that apply to regular interfaces, such as QoS, can be applied to VPLS service endpoints.
