It is clearly indicated that the draft does not deal with measurements which means no recommendation is made.

If your question is related to configuration and implementation of measurements, well it will not be addressed by this draft.

Re: [Lsr] IGP TE Metric Extensions
Thanks, Jeff. Would be good to have this clarified in draft-ginsberg-isis-rfc7810bis. My original message seems to have been stripped off, so including it again for the lsr list.. Both RFC 7810 and RFC 7471 say that: The measurement interval, any filter coefficients, and any advertisement intervals MUST be configurable per sub-TLV. Additionally, the default measurement interval for all sub-TLVs SHOULD be 30 seconds. However, both RFCs initially say that they only describe mechanisms for disseminating performance information and methods of measurements is outside their scope. Moreover, for a first time reader, it seems to suggest that the measurement interval and filter coefficient must be supported and configurable under the IGP. In a system supporting multiple IGPs, I would expect that they be implemented outside the IGP and the IGPs just disseminate the information provided to them. Thoughts, especially from an implementation standpoint? Regards.
