ARP timeout in broadcast message
<p>Suppose i have source host H1(10.1.1.2/24) who wants to communicate to host H2(10.1.1.3/24). Since both hosts are in same subnet H1 sends a ARP broadcast. H2 replies to this broadcast and finally H1 gets H2 MAC address. Consequently communication establishes.</p>

<p>Now if H2 is down, H1 is not going to receive ARP reply from H2. So for what duration H1 will wait for ARP reply? RFC 826 does not talk about any such timer.</p>

<p>I found in some forum that it is 5 to 30 seconds. Is it correct?</p>
