The easiest way would be to create a VLAN interface (e.g. eth0.50) for use as your management/API network as well as your VXLAN VTEP address, or you can create a separate interface for that. You will then use eth0 for your provider bridge interface (e.g. physical_interface_mappings = physnet1:eth0). You can then create a single flat and multiple VLAN provider networks using --provider:physical_network=physnet1 and segmentation IDs other than 50. The LinuxBridge agent will create VLAN interfaces and place them in the respective bridges.<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='color:black'>James<o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='color:black'><o:p> </o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='color:black'><o:p> </o:p></span></p></div></div><div><p class=MsoNormal><span lang=EN-US style='color:black'><o:p> </o:p></span></p></div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal><b><span lang=EN-US style='color:black'>From: </span></b><span lang=EN-US style='color:black'>liyulei <</span><span lang=EN-US><a href="mailto:liyulei_walker@hotmail.com">liyulei_walker@hotmail.com</a><span style='color:black'>><br><b>Date: </b>Thursday, April 14, 2016 at 3:17 AM<br><b>To: </b>"</span><a href="mailto:openstack@lists.openstack.org">openstack@lists.openstack.org</a><span style='color:black'>" <</span><a href="mailto:openstack@lists.openstack.org">openstack@lists.openstack.org</a><span style='color:black'>><br><b>Subject: </b>[Openstack] [OpenStack] How to deploy Liberty Neutron with linuxbridge on physical machine having single NIC</span></span><span lang=EN-US style='font-size:12.0pt;color:black'><o:p></o:p></span></p></div><div><p class=MsoNormal><span lang=EN-US style='color:black'><o:p> </o:p></span></p></div><p class=MsoNormal><span lang=EN-US style='color:black'>Hello,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'>Is it possible that deploying Liberty Neutron with linuxbridge on physical machine having single NIC ?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'>If it is, how should do ?<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'>Thanks<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'> <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='color:black'>Li yulei<o:p></o:p></span></p></div></body></html>
