The IETF TRILL (Transparent Interconnection of Lots of Links) base
protocol specifies minimal hooks to safely support TRILL Header
extensions. This document specifies an initial extension providing
additional flag bits and specifies two of those bits, plus the
Critical Channel Alert Flag used by the channel draft.
Working Group Summary
There was rough consensus in the working group in favor of the
document, with one relatively strong dissenter. The main point of
the dissenter was that the material in this draft is not needed to
provide an RBridge channel that can be used for BFD and error
reporting, hence the extensions are speculative on future
standardization that would make use of them. The WG neverless wants
to proceed with this document.
The document has been carefully reviewed in the WG and by the
document shepherd. There are no known implementations of the
additional Critical Channel Alert Flag specified in this document.
Erik Nordmark is the Document Shepherd. Ralph Droms is the
responsible Area Director.
