Thanks. </div><div><br></div><div>But I have some questions about the demo in the topic. </div><div><br></div><div>I do some steps according to the topic. </div><div><br></div><div>First, creating two networks like this:</div><div><br></div><div><div>neutron net-create multinet --shared --segments type=dict list=true provider:physical_network=phys<wbr></wbr>net1,provider:segmentation_id=<wbr></wbr>2016,provider:network_type=vla<wbr></wbr>n provider:physical_network=phys<wbr></wbr>net2,provider:segmentation_id=<wbr></wbr>2016,provider:network_type=vla<wbr></wbr>n</div></div><div><br></div><div><br></div><div>Second, I get two segments after creating this network. I get these segments by using " openstack network segment list ". </div><div><br></div><div>Third, I create two subnets by these segments by using this command " </div><div><br></div><div><div>neutron subnet-create --ip_version 4 --name multi-segment1-subnet [net-id] <a href="http://10.1.0.0/24" target="_blank">10.1.0.0/24</a> --segment_id [segment-id]</div><div>neutron subnet-create --ip_version 4 --name multi-segment2-subnet [net-id] <a href="http://10.1.1.0/24" target="_blank">10.1.1.0/24</a> --segment_id [segment-id]</div></div><div> "</div><div><br></div><div>At last, I want to create a port with host_id. My local environment contains two compute nodes, one is named "devstack" and the other is "devstack2". So I use this command " neutron port-create --binding:host_id=devstack [net-id] ". </div><div><br></div><div>Exception happens in neutron server. The exception says "</div><div><br></div><div>Host devstack is not connected to any segments on routed provider network [net-id]. It should be connected to one." I can not get this exact point about this exception. </div><div><br></div><div>Why does the "routed network" have relationship with host? </div><div><br></div><div>How they work together between "host info (compute node ?)" and "routed network"?</div><div><br></div><div>What should I do if I want to get rid of this exception?</div><div><br></div><div><br></div><div>Hope for your reply. Especially Carl and Miguel. ;-)</div><div><br></div><div><br></div><div><br></div><div>Many Thanks</div><div>Zhi Chang</div></div>
