Hi, OPS-DIR, Authors,

I have reviewed this document as part of the Operational directorate's ongoing
effort to review all IETF documents being processed by the IESG. These comments
were written with the intent of improving the operational aspects of the IETF
drafts. Comments that are not addressed in last call may be included in AD
reviews during the IESG review. Document editors and WG chairs should treat
these comments just like any other last call comments.

This Standards Track 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. This document is well written. I don't see any
major issues from the operations and management perspective. It is ready to be
published. There are a couple of minor comments below:

1) (minor but must be solved before publish) in the figure 8 and figure 9, VLAN
IDs are presented in 2 octets. How the current 12-bit VLAN ID is expanded into
16 bits MUST be clearly defined. Otherwise, implementation may have different
choice. It would create interoperation issues.

2) a couple of abbreviations do not have their full name for at least once:
BRG, PWid.

Best regards,

Sheng
