Re: Last Call: Routing IPv6 with IS-IS to Informational

[Bill Fenner <fenner@research.att.com>]

Bob,

  Many IS-IS documents come out as informational because they are
technically submissions from the IETF to ISO/IEC JTC1, since they
modify the ISO IS-IS spec.  We've written down exactly which documents
the IETF can publish on the standards track, but this document was
in progress before that agreement was reached and we didn't want to
derail its progress by re-casting it as Proposed.  (It's also not
clear that it could go Proposed anyway, since it depends heavily on
the traffic engineering spec, which is not completely on the IETF
side of the fence.)
