<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666">Hi Mark et al, thank you for your help the other day. I'm still a bit stuck with this one and I am trying to test the octavia network by deploying a regular openstack instance onto it (CentOS7) which is failing. In fact, my other and currently "working" external network is also failing to deploy instances directly onto this neetwork also. So I am wondering if there's some other step which I am missing here. Completely forgetting about the octavia network, I'm curious to understand why deploying instances to an external network has always failed for me. I have a network like this: </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666">Real network switch VLAN 20 ----> openstack external network "br-ex" (<a href="http://192.168.20.0/24)----openstack">192.168.20.0/24)----openstack</a> router----- openstack vxlan local network (<a href="http://172.16.1.0/24">172.16.1.0/24</a>)</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666">I can successfully deploy instances onto <a href="http://172.16.1.0/24">172.16.1.0/24</a> but always fail when attempting to deploy to <a href="http://192.168.20.0/24">192.168.20.0/24</a>.</div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666">The octavia network is almost a mirror of the above except that the controller also has an IP address / ip interface onto the same. But forgetting about this, would you happen to have any ideas or pointers that I could check that could help me with regards to why I am unable to deploy an instance to <a href="http://192.168.20.0/24">192.168.20.0/24</a> network? There is a DHCP agent on this network. When I try and deploy an instance using Horizon, the dashboard shows that the instance has an ip on this network for a brief moment, but then it disappears and soon after, fails with an error that it cannot plug into it. The understanding / expectation I have is that the instance will run on the compute node and tunnel the network back to the network node where it will be presented onto <a href="http://192.168.20.0/24">192.168.20.0/24</a>. Does the compute node also need an ip interface within this network to work? I ask this because the octavia network did indeed have this but it was too failing with the same error. </div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666"><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;color:#666666">Any pointers appreciated so I can try and keep my hair.
