I am running radvd v. 1.7 and I am wondering about its replies to Router Solicitation messages. Am I right in thinking that radvd should respond to any Router Solicitation messages that it sees? Does it respond instantaneously or with a certain delay? </p>

<p class="MsoNormal"><br>Hi Panos,<br><br>RADVD does not send a response to every solicitation and there is a random delay (between 0 and 1/2 seconds I think). The random delay is called for in RFC 2461 (<a href="http://www.faqs.org/rfcs/rfc2461.html" target="_blank">http://www.faqs.org/rfcs/rfc2461.html</a>). It's not really that important, but it cuts down on the number of broadcast advertisements needed.<br>
<br>RADVD should NOT respond to every solicitation it sees (we don't want to flood the network with useless advertisements). However, if you're finding you don't get an address fast enough, then you may have a bug or configuration issue.<br>

<p class="MsoNormal"><span style="font-size: 11pt; color: rgb(31, 73, 125);"> Thanks for your reply, it is really helpful. Is there any flag that sets the maximum response delay to a solicitation ? How can we learn what is the maximum delay right now, so that I can identify whether I have a bug or a configuration issue.</span></p>
