Why you got two IPs on same interface with different netmasks?<br>
<br>
I just rechecked it on our installations - it should not be happens.<br>
<br>
Next: or this is a bug, or this is uncleaned network node (lesser
bug), or someone messing with neutron.<br>
<br>
Starts from neutron:<br>
<br>
show ports for router:<br>
<br>
neutron port-list --device-id=router-uuid-here<br>
neutron floatingips-list<br>
neutron net-list<br>
neutron subnet-list<br>
(trim to related only)<br>
<br>
(and please mark again who is 'internet' and who is 'internal' ips,
i'm kinda loosing in '192.168.*'.<div><div><br>
