---------- Forwarded message ---------- From: Robert Raszuk <robert@raszuk.net> Date: Thu, Jan 4, 2018 at 10:48 PM Subject: Re: [Rift] kicking off the charter discussion To: Alia Atlas <akatlas@gmail.com> Cc: rift@ietf.org Hi Alia, Do we really need yet one more new routing protocol vs relatively minor extension of existing link state protocols ? In the light of recent proposal of dynamic flooding I am completely not convinced there is need to discuss rift charter.
