<br><br><div dir="ltr"><div><div><div><div><div><div><div><div>Hi,<br><br></div>I was able to solve all the problems that I had with getting one flat network in the same subnet as I have a router in - <a href="http://192.168.22.0/24" target="_blank">192.168.22.0/24</a>. Instances successfully get IP addresses in the desired pool and the communication works perfectly.<br>
<br></div>As an "upgrade" to that I still want to use my public IP subnet (<a href="http://102.203.103.80/29" target="_blank">102.203.103.80/29</a>) directly on the instances. <br><br>I have now changed two lines in ovs_neutron_plugin.ini to:<br>
network_vlan_ranges = physnet1,physnet2<br>bridge_mappings = physnet1:br-em1,physnet2:br-em2<br><br>and created new bridge br-em2 on compute and controller nodes. <br><br></div><div>I have connected em2 to a separate port on the HW switch.<br>
<br></div></div>Network and subnet via neutron are created successully (network is using physnet2) and I can ping the hw router's default gateway from DHCP server's namespace:<br><br></div>However, there are absolutely no DHCP DISCOVER messages from the instance in the syslog as they are for the first flat network.<br>
<br></div>I can see in neutron's server.log that two physnets (physnet1 and physnet2) are created successfully and since the first one is working I have no ideas why the second - physnet2 doesn't.<br><br></div>Any ideas on where to look and what to do will be very welcome :)<br>
</div>TIA, Matej<br></div>
