[major] For *-timer: Is tracking the remaining time in seconds enough? I
would assume that ms would be the right unit. Why seconds?
<acee> Because sub-second hellos was a bad idea – three words: B-F-D…'
This question is not about sub-second Hellos…it’s about the *remaining
time*. Even if Hellos are x seconds apart, the “remaining time before the
neighbor is declared dead” can still be in ms, right? Why not? Note that
there are other places in the model that are characterized as tracking the
remaining time.
I don’t feel that strongly. However, it would seem that one would use the
same granularity as the configuration. No?
I wouldn’t think so. If I was an operator I would like to know if there
are 500ms left before my neighbor dies, and not just 1 or 0. I think this
may also be useful for troubleshooting.
But I’m not an operator…
Alvaro.
We found that the RFC 8294 timer types aren’t good for “config true” values
since the values “infinity” and “not-set” are included in the union. Hence,
they lend themselves better to operational state than configurable values.
