Sure ... In the current version of the doc, option A is : single ‘tag’ type which can represent a protocol tag (it's only related to IGP tags in the draft)
So I would be in favor of option C :) (slight variation of option A) which is really single ‘tag’ type which can represent a protocol tag, or some purely local ‘colour’ attribute. -----Original Message----- From: Rob Shakir [mailto:[email protected]] Sent: Tuesday, July 21, 2015 16:30 To: LITKOWSKI Stephane SCE/IBNF; Jeffrey Haas Cc: [email protected] Subject: RE: Comments on draft-shaikh-rtgwg-policy-model Folks, There’s some ambiguity in the discussion here, from my perspective: Option A: single ‘tag’ type which can represent a protocol tag, or some ‘colour’ attribute. Option B: multiple ‘tag’ types, a generic ‘colour’ and then per-protocol tags. Right now, oc-policy uses option A. I can see arguments for either - but Stephane I was not clear from your view which of these you prefer - can you clarify for me please? Thanks, r.
