[mpls] Question raised in the MPLS-RT review of draft-rosen-mpls-rfc3107bis

[Loa Andersson <[e-mail]>]

Eric, et.al., (copied also idr-chairs and idr-list + bess-chairs and
bess-list)

For those of you that are not subscribed to the mpls-list.

- the mpls wg has started the initial steps for working group adoption,
   there are three steps
   -- mpls-rt review (what you see below is the follow-up discussion on
      that review)
   -- IPR poll, will be sent out soon
   -- working group adoption poll (wgap), that poll will be copied to
      the idr and bess. Hopefully we can that shortly.

I'm sending this to mpls, idr and bess working group, since it has
to do where things should be documented.

I agree that this needs to be documented! I can accept that it is done
in draft-rosen-mpls-rfc3107bis, but I would like to have all three wg's
agree to this. I see a few alternatives

- we could document this is in draft-rosen-mpls-rfc3107bis; or
- we could write a separate document
- we could find another document where this has a better fit than in
   draft-rosen-mpls-rfc3107bis
- any other suggestion

Let us know if you have an opinion.

Please send your responses to the mpls wg mailing list ([e-mail]).
