Re: [Bier] WG adoption call for draft-chen-bier-frr-02

[Tony Przygienda <[e-mail]>]

Excellent, having authors of multiple drafts in this area co-allesce and
colaborate on a single framework document would be a very positive and
productive development in my eyes. If it explains the IGP model e'one uses
today so far and the architecture kind of implies as default with IGP
signalling, the better.

Discussions around informational/experimental can happen later of course
but generally experimental will introduce the burden of two implementations
most likely (and with that many models that may not be trivial) and of
course experimental is needed in case we end up allocating codepoints or
need to agree on some on-the-wire formats (algorithms are not that clear).
We play it by the ear depending on the scope of the document as it evolves
and content would be my take for now.

thanks
