[mpls] draft-liu-mpls-tp-bnm-00.txt - was no subject

[Stewart Bryant <[e-mail]>]

The draft is at

http://www.ietf.org/internet-drafts/draft-liu-mpls-tp-bnm-00.txt

A few points

The A bit mechanism is not the mechanism that is described in the latest
version of draft-ietf-mpls-tp-gach-gal. Instead you need to define the
type to always have an TLV, but set the TLV length to zero in the
TLV header when no TLVs are needed.

We need to consider the overlap with draft-boutros-mpls-tp-xxx-00.txt
series of drafts and should look to merge the appropriate content.

I am not sure at this stage why we need vendor specific and/or
experimental types. At best I think we only need one, but
I think experiments should be conducted on the experimental
ACH code point.

There is no explaination of the operation of the CSF and
fault TLVs.

Regards

Stewart
