We do design protocols to operate in a given environment though, and IS-IS doesn't require a synchronized clock at all, just a roughly syntonized one. If we were to add such a requirement, I'd be raising serious concerns at this point. For a debugging aid, I don't care, I'm just pointing out what current reality looks like. I'll also point out that if a router acquires its clock primarily from NTP, it has no way of getting at the TAI-UTC offset from there. NTP only carries differential leap seconds signalling, i.e. +1/-1 "as it happens". It would need to consume a tzdb leap-seconds file from somewhere else, which if the stack doesn't implement PTP, it might not even have an option for. -equi _______________________________________________ Lsr mailing list -- lsr@ietf.org To unsubscribe send an email to lsr-le...@ietf.org
