Dear members:
I agree with Karl that one end of the time interval is when the router sent its
most recent Router Advertisement, and that interval must be less than
MIN_DELAY_BETWEEN_RAS.
My question was about the other end of the interval.
Is it the computed value in the first paragraph (a random value plus the
reception of the Router Solicitation), or is it the reception of the Router
Solicitation?
I think it should be the computed value, but in the text it seems to be the
reception of the Router Solicitation.

The question is about the second paragraph: “within the last ...”
When does the time start? Does it start from the reception of the Router
Solicitation or from the computed value in the first paragraph?
My interpretation is as follows:
The time started when the router *sent* its most recent Router
Advertisement.
As the name suggests, the period is the "minimum delay between router
advertisements". It's designed to rate limit RAs. If the random delay
would result in sending an RA inside that time, ignore the random delay.
