<p dir="ltr">I'm integration RDO (Packstack) Openstack with OVN and facing a problem connecting DVR to external networks. My setup consists of a couple of virtual networks and a router interconnecting them. On each compute node I've create a "br-ex" and created a mapping "ovn-bridge-mappings=extnet:br<wbr>-ex". I've also created a neutron network with "--provider:physical_network extnet" and assigned this network as a gateway to my router. I can see that OVN northDB creates a new LS with two ports as expected:</p>
<p dir="ltr"> switch 151ac068-ee99-4324-b785-40709b<wbr>2e2061 (neutron-b4786af5-cf70-4fc2-8f<wbr>36-e9d540165d37)</p>
<p dir="ltr"> port provnet-b4786af5-cf70-4fc2-8f3<wbr>6-e9d540165d37</p>
<p dir="ltr"> addresses: ["unknown"]</p>
<p dir="ltr"> port fb73ca73-488f-40aa-89e1-e8e312<wbr>de7a77</p>
<p dir="ltr"> addresses: ["fa:16:3e:1d:75:66 169.254.0.50"]</p>
<p dir="ltr">However, I can't see any link between my DVR and this LS. Am I expected to create a DVR-to-extLS patch manually?</p></blockquote></span></span><div>What version of networking-ovn are you using? To do this, you need networking-ovn from master (ocata).<br></div><span class=""><span><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<p dir="ltr">Can you also clarify one more thing. I've seen the setting for L3 gateway scheduling which, I assume, should place that external router IP (169.254.0.50 in my case) on a particular compute node. Is there any document that describes what happens during GW scheduling?<br></p></blockquote></span></span><div>Right now scheduling is primitive. It uses a "least loaded" scheduling policy to distribute gateways among the available chassis.
