Timers on info stored by hosts 

The draft doesn't currently specify how hosts should age the
information they collect about prefixes active on a link.

Today JinHyeock suggested three times the maximum value of
MaxRtrAdvInterval (3 * 1800 sec = 1.5hr) as an expiry time for
unrefreshed data.  I said that when an Advertisement Interval
option is present in the RA, a multiple of that could be used.

Any support for 1.5hrs?  Any support for allowing 3 times the
Advertisement Interval, if present, as an optimization?

This sounds fine. It's just a default, after all.

I don't think the number should be coupled to the advertisement interval, since that number says how often RAs are sent, and not how quickly the a flush renumbering followed by reassignment to a different link might happen.
So picking some reasonable fixed constant for this is fine.
1.5 hours is within my range of comfort.

I think this one's resolved:

Yes for 1.5 hours.
No for using the advertisement interval.
