WGLC for BFD Multipoint documents (ending July 14, 2017)

[Jeffrey Haas <[e-mail]>]

Working Group,

https://tools.ietf.org/html/draft-ietf-bfd-multipoint-10
https://tools.ietf.org/html/draft-ietf-bfd-multipoint-active-tail-04


The BFD Multipoint documents have been stable for some time.  Prior
discussion at meetings has suggested we have an implementation for the main 
protocol component.  Also per prior discussions, we split the active-tail
component of the original multipoint document to permit implementors to not
have to worry about implementing active-tail procedures if they weren't
interested in that feature.

We are starting an extended last call on these documents.  The WGLC will
conclude on July 14.  This provides ample time for list discussion.  If
necessary, the IETF-99 meeting may provide for opportunities to close any
contentious technical points.  (BFD is not currently scheduled to meet.)

One item I would like to kick off is the document status of the active-tail
mechanism.  At this time, no one has implemented it that I am aware of.
Discussion with our AD suggests that publishing the document with
Experimental status may be reasonable to preserve the work that went into
the proposal.
