This document specifies a generic Virtual Private LAN Service (VPLS)
solution, which uses VLANs to indicate root or leaf traffic to
support Ethernet-Tree (E-Tree) services.  A VPLS Provider Edge (PE)
model is illustrated as an example for the solution.  In the
solution, E-Tree VPLS PEs are interconnected by Pseudowires (PWs),
which carry the VLAN indicating the E-Tree attribute.  The MAC
address-based Ethernet forwarding engine and the PW work in the same
way as specified in RFC 4762 and RFC 4448, respectively.  A signaling
mechanism is described to support E-Tree capability and VLAN mapping
negotiation.

This document is a product of the Pseudowire And LDP-enabled Services Working Group of the IETF.

This is now a Proposed Standard.
