Jeff, All,

we have added many extensions to IGP protocols over the years. Many times multiple solutions were proposed for the same or similar problem and WG picked from the set, many times multiple solutions were merged or combined together. We never asked for a requirement document. Even for more significant changes then we are talking about here.

I understand that the area of DC routing using IGPs is a broader area, but it does not fundamentally change IGPs to warrant the need for requirement document as a prerequisite to move forward with any work that is related to any optimization that may be applicable to DC environment.

So while I'm not against the existence of the document that would cover the requirements for IGPs in DC environments , I don't believe we should gate all proposed work in this space by such a document. And to be completely honest, the requirements are pretty straightforward for anyone that is familiar with the protocols' operation.

my 2c,
Peter

We could start with a document, similar to dc-routing requirements one
we did in RTGWG before chartering RIFT and LSVR.
Would help to disambiguate requirements from claims and have apple to
apple comparison.
Doing it on github was a good experience.

Jeff

At IETF 102, there was no dearth of flooding reduction proposals.  In
fact, we have so many proposals that there wasn’t agree as how to
move forward and we agreed to discuss on the list. This Email is to
initiate that discussion (which I intend to participate in but as a
WG member).


Hi Acee,

Perhaps a useful starting point of the discussion is to talk about
requirements.  There seem to many different perceptions.

Regards,
Tony
