<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi,</span>
<br>
<br>
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">While working on the integration of Openstack With ODL GBP, I have the below queries:</span>
<o:p></o:p></p>
<ol start="1" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo2">
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Endpoint-group Create: When I create a new policy-target-group from Openstack say "gbp target-policy-group-create group1", it internally creates a l2.policy which includes the creation of the network
and subnet. Meaning creation of EPG will create Network and subnet implicitly in Openstack and also the corresponding EPG, subnet, l3-context, l2-flood-domain, l2-bridge-domain will be created in the ODL GBP.
<b>So during the above EPG creation, neutron network and subnet call will come to the neutron northbound of ODL or only to ODL GBP??</b></span>
<o:p></o:p></li></ol>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">[Yapeng] First, when creating policy-target-group, you need to give “provided-policy-rule-sets” or
“consumed-policy-rule-sets” parameter. Currently we don’t support policy-target-group update. Second, neutron network and subnet call won’t go to ODL.<o:p></o:p></span></p>
<ol start="2" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo3">

<ol start="2" type="1">
<li class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l0 level1 lfo4">
<span style="font-size:10.0pt;font-family:"Arial","sans-serif"">In ODL, there is no Endpoint create API, instead there is an API to register the endpoints<b>. So what is the sync between the OS and ODL for Endpoint create and register.?</b></span><o:p></o:p></li></ol>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif";color:#1F497D">[Yapeng] The current working scheme is as follow: ODL GBP has new APIs for openstack-endpoint register and unregister supports.[1][2] When Openstack GBP creates
policy-target, a neutron port will be created by implicit driver, openstack-endpoint register API will be invoked and the OVS tap-port-id will be passed as parameter to ODL GBP. Later when VM is booted, the OVS tap-port-id will be populated on openvswitch,
this will trigger ODL to update ovs flow tables.<o:p></o:p></span></p>

Hi, This GBP spec is currently being worked on:</span><u><span style="color:blue"><br>
</span></u><a href="https://review.openstack.org/#/c/134285/"><span style="font-size:10.0pt">https://review.openstack.org/#/c/134285/</span></a><span style="font-size:10.0pt"><br>
<br>
It will be helpful if you can add "[Policy][Group-based-policy]" in<br>
the subject of your emails, so that the email gets characterized<br>
correctly.<br>
<br>
Thanks,<br>
