I support the progression of this draft. Though I have few 
queries/clarifications:

Is the definition of a link restricted to the underlay physical links or also 
mapped to logical ones like  TE-links mapping to a tunnel.
For example, a bandwidth tied to a VPN tunnel stitching two fabrics over WAN. 
(like a multisite deployment).

Can we clarify the definition of the “link” if it’s not implicit.

Thanks,
Saumya.

IDR has started the working group last call covering the link bandwidth 
feature.  Since this draft overlaps with other work done or proposed in BESS, 
please participate in this last call on the IDR mailing list.

This begins the working group last call for the link bandwidth extended 
community draft.  Thanks to the authors for working their way through the 
substantive items that have been obstacles to interoperability over the years.

This last call ends a week after IETF 123 to give the working group time to 
review and also take advantage of the focus time that IETF meeting weeks bring 
to our work.

An item in particular we'd like to request particular attention to from the 
working group's review are the procedures covering default behaviors and 
interactions with deployments with mixed transitivities.  The current draft 
text works to try to accommodate maximal backward compatibility with various 
deployment scenarios, but such text is tricky.

For purposes of the shepherd's report and according to IETF BCP 78/79, the 
authors are requested to declare whether they are aware of any undisclosed IPR 
covering this draft. Members of the working group are similarly obligated to 
report any they are aware of as well.
