Hi Muthu, The Sections 5, 6 and 7 of these drafts are critical as it impacts the IGP protocol operation and stability though it is not an integral part of the IGP protocol machinery. This functionality in a system, whether achieved in the IGP/measurement/some-other module, is an implementation

Sounds reasonable to me.. Adding a clarification note in the draft would be useful, IMHO. Regards, Muthu On Tue, Jun 5, 2018 at 5:00 PM, Ketan Talaulikar (ketant) wrote: > Hi Muthu, > > > > The Sections 5, 6 and 7 of these drafts are critical as it impacts the IGP > protocol operation and stab

If these are only implementation specific aspects and shouldn't get into the draft, what is the point of sections 5,6,7? Why would it hurt to say what is generally expected to be part of the protocol machinery and what is not? BTW, any known implementation for RFC 7810, also supporting sections 5,

Hi Muthu, The sections 5,6,7 specify the required aspects that an implementation needs to take care of (with all its normative language) - it specifies the “WHAT” part. Your questions were related to the “WHERE” and “HOW” parts for the same (e.g. when you asked “configurable under IGP” and “out

Muthu – I agree with the comments from all of the folks who have responded to you thus far. The RFC is specifying what the externally visible behavior needs to be in order for the feature to be safely and usefully deployed – it is not specifying HOW to implement that behavior. But, let’s assum
