Dear members:
I have a question about the Router Advertisement sending algorithm of RFC 4861.
On page 49, it states:
“A router might process Router Solicitations as follows:
- Upon receipt of a Router Solicitation, compute a random delay
within the range 0 through MAX_RA_DELAY_TIME. If the computed
value corresponds to a time later than the time the next multicast
Router Advertisement is scheduled to be sent, ignore the random
delay and send the advertisement at the already-scheduled time.
- If the router sent a multicast Router Advertisement (solicited or
unsolicited) within the last MIN_DELAY_BETWEEN_RAS seconds, ...”
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?
