Ross, thanks for this notice.
I need to read the IPR referenced by the disclosure, but pending that, I do not
support this document going forward in its current state.
I think it is important for the working group to seek to develop solutions that
either completely unencumbered by IPR or that is available on
free-to-implementers terms. It may turn out that this is not possible with the
disclosed IPR, but I think the WG should try.
For the avoidance of doubt: I am not making any comment on the IPR-holder's
rights to impose whatever license they want, and I am not asking them to vary
their terms. 
I do not that it would be convenient if the IPR holder updated the disclosure to
show that it applies to the current WG draft.

Working Group,
This is to initiate a two week working group last call on
Please send your comments to the mpls wg mailing list ( <>
There is one IPR disclosure on draft-mirsky-mpls-bfd-directed 
(which was the pre-working group version of draft-ietf-mpls-bfd-directed): 

All the authors have stated that they are not aware of any other IPR that
relates to this
This working group last call will end at the end of the day Friday March 25,
As with any WGLC, working group participants are requested to read the document 
and comment. If you feel that the document is ready for publication it is
appropriate to 
respond to any WGLC with a short and simple email indicating support. 
for the MPLS WG chairs
