Specifically, they find paths between l2_multi's Switch objects (I think if you'd printed the contents of path_map, this would have become apparent). A separate dictionary object (mac_map) keeps a mapping between an Ethernet address and which Switch it thinks is associated.<div><br></div><div>-- Murphy</div><div> <br><div><div>On Nov 13, 2013, at 11:07 AM, AMER <<a href="mailto:amer7777@hotmail.com">amer7777@hotmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div class="hmmessage" style="font-size: 12pt; font-family: Calibri; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;"><div dir="ltr">Hello,<br> <br>Pox.py<span class="Apple-converted-space"> </span><em>forwarding.l2_multi openflow.discovery</em><br><em>tree topology with no loops</em><br><em></em> <br>I want to get the path from source to destination using l2_multi, I tried with:<br>src = "10.1.1.1"<br>dst ="10.2.2.2"<br>path_info = _get_raw_path(src, dst)<br>print path_info<br>but I have got None, while i can ping these two hosts.
