<div dir="ltr"><div>I have dedicated controller, compute and networking nodes running on Ubuntu12.04 with Havana. The problem is on Neutron node, when I create a router and attach a public and private network to it. I am using VLAN to connect nodes.<br>
<br>The findings are<br>
1. The tap and qr ports connected to br-int are always down.<br># ovs-ofctl show br-int<br>OFPT_FEATURES_REPLY (xid=0x2): dpid:00004e07ed035c4c<br>n_tables:254, n_buffers:256<br>capabilities: FLOW_STATS TABLE_STATS PORT_STATS QUEUE_STATS ARP_MATCH_IP<br>
