Technical Summary
A generic Virtual Private LAN Service (VPLS) solution is specified
for Ethernet-Tree (E-Tree) services which uses VLANs to indicate
root or leaf traffic. A VPLS Provider Edge (PE) model is illustrated
as an example for the solution. In the solution, E-Tree VPLS PEs are
interconnected by 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 before. A signaling mechanism for E-Tree
capability and VLAN mapping negotiation is further described.
Working Group Summary
Progress through the working group was unremarkable until the end,
when some discussion arose around the dynamic reconfiguration of
the etree. It was determined that there was no requirement for
seamless dynamic reconfiguration, although there was a need to
be able to correct an incorrect configuration. Text was added to state
this constraint and to provide guidance on how to ensure that the
system automatically recovered to a state of correct operation in
these circumstances.
