Yes, that's the bug that occurred to me too, for your symptom. I think that including that patch will solve the problem.

The router seems correctly schedule to the agent. After doing more tests, I realised the issue also happens when I try to link a new floating-ip. This is the log:<br>
<small>Command: ['sudo', 'neutron-rootwrap', '/etc/neutron/rootwrap.conf', 'ip', 'netns', 'exec', 'qrouter-84a23b9d-cf74-435c-99a1-53b842209c73', 'ip', '-4', 'addr', 'add', '192.168.7.204/32',
<b>'brd', 'None'</b>, 'scope', 'global', 'dev', 'qg-ee3cf43a-10']<br>
Exit code: 1<br>
Stdout: ''<br>
Stderr: 'Error: an inet address is expected rather than "None".\n' execute /usr/lib/python2.7/site-packages/neutron/agent/linux/utils.py:75</small><br>
<br>
I see that a broadcast address is expected, for instance <br>
<br>
<small>ip netns exec qrouter-84a23b9d-cf74-435c-99a1-53b842209c73 ip -4 addr add 192.168.7.204/32
<b>brd 192.168.7.255</b> scope global dev qg-ee3cf43a-10</small><br>
<br>
I continue searching for any solution.<br>

<div bgcolor="#FFFFFF">Hi all<br>
<br>
After a downtime of neutron I noticed that the floating-ips (already created) are not included as interfaces in qrouter. The iptables in qrouter were perfectly set.
<br>
<br>
<small># ip netns exec qrouter-84a23b9d-cf74-435c-99a1-53b842209c73 iptables-save | grep 192.168.7.204<br>

#<small> </small><b>(no ip)</b></small><br>
<br>
Any idea to force the reload of these (floating-ips) interfaces in qrouters? (restarting the l3 agent doesn't solve the issue)<br>
