Hi Uma, I have just posted the new rev that includes your change. Brgds, -----Original Message----- From: rtgwg [mailto:rtgwg-bounces@ietf.org] On Behalf Of Uma Chunduri Sent: Thursday, January 18, 2018 02:32 To: Chris Bowers Cc: rtgwg-chairs; RTGWG Subject: RE: WG last call for draft-ietf-rtgwg-spf-uloop-pb-statement Hi Chris and Co-authors, Something to this spirit before the last bullet point in Section 2. o SPF computation order: A SPF trigger can be common to multiple IGP areas or levels (e.g., IS-IS Level1/Level2) or for multiple address families with multi-topologies. There is no specified order for SPF computation today and it is implementation dependent. In such scenarios, if the order of SPF computation done in A and B for each area/level/topology/SPF-algorithm is different, there is a possibility for a micro-loop to appear. BR, -- Uma C. -----Original Message----- From: Chris Bowers [mailto:chrisbowers.ietf@gmail.com] Sent: Tuesday, January 16, 2018 1:49 PM To: Uma Chunduri <uma.chunduri@huawei.com> Cc: RTGWG <rtgwg@ietf.org>; rtgwg-chairs <rtgwg-chairs@ietf.org> Subject: Re: WG last call for draft-ietf-rtgwg-spf-uloop-pb-statement Uma, Could you propose some specific text to add to the document to address your comment?
