--------------------------------------
Type: Technical
Reported by: Alexander ("Sasha") Vainshtein <[email-masked]>

Section: 6

Original Text
-------------
N/A - this is about some missing MIB objects that should be there

Corrected Text
--------------
N/A - this is hardly the right place to define missing MIB objects

Notes
-----
As per RFC 4762 (which defines at least one of the two VPLS types for which this RFC defines Management Information Base), Virtual Switching Instance (VSI)(a local representation of a given VPLS instance within a given PE) is connected to CE devices via Attachment Circuits (AC). Hence I would expect that Management Information Base for VPLS would provide for some representation of ACs that perform this function for a given VSI.

However, this RFC does not even mention attachment circuits in any way.

I have tried to raise this issue with the WG and the authors. One of the authors has replied (see http://www.ietf.org/mail-archive/web/l2vpn/current/msg04539.html) that "ACs are attached to the VPLS instances and are represented as IfMIB entries". However, neither Interfaces MIB nor any of its key elements (e.g., ifIndex) are mentioned in this RFC.

Instructions:

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
