<div dir="ltr">Hi, shihanzhang.<div><br></div><div>I still have a question about routed network. I have two subnets. One is <a href="http://10.1.0.0/24">10.1.0.0/24</a> and the other is <a href="http://10.1.1.0/24">10.1.1.0/24</a>. I create two instances in each host.</div><div>Such as 10.1.0.10 and 10.1.1.10.</div><div><br></div><div>My question is, how does 10.1.0.10 connect to 10.1.1.10 ? There is no any gateway( 10.1.0.1 and 10.1.1.1 ) in each subnet.</div><div><br></div><div><br></div><div>Hope four your reply. ;-)</div><div><br></div><div><br></div><div>Thanks</div><div>Zhi Chang</div></div><div class="gmail_extra"><br><div class="gmail_quote">2016-11-01 14:31 GMT+08:00 zhi <span dir="ltr"><<a href="mailto:changzhi1990@gmail.com" target="_blank">changzhi1990@gmail.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Hi, shihanzhang.<div><br></div><div>Thanks for your advice.

Carl and Miguel made this topic. I learned a lot of your topic. 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>net1,provider:segmentation_id=<wbr>2016,provider:network_type=vla<wbr>n provider:physical_network=phys<wbr>net2,provider:segmentation_id=<wbr>2016,provider:network_type=vla<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>
