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, Muthu
