<p class="MsoPlainText">Hi keshava,<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">I've tried to answer your questions, but I am not confident about your use case. Can you explain me, please? Or ping me anytime at irc (my nickname is devvesa)<o:p></o:p></p>

<p class="MsoPlainText">Line 120: namespace in the compute node.<o:p></o:p></p>
<p class="MsoPlainText">> Please make it clear: If DVR is turned-on BGP can be enabled or not ?
<o:p></o:p></p>
<p class="MsoPlainText">BGP can be enabled. However, I think this paragraph crosses concepts that may confuse people. I will delete in the next patch.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Line 123: to an upstream router. It does not require learning routes from the upstream<o:p></o:p></p>
<p class="MsoPlainText">> Is it possible how to block learning from upstream peer router ?<o:p></o:p></p>
<p class="MsoPlainText">Yes, is absolutely configurable. If you see the RoutingInstance entity down below, you will see that you can choose either you want to learn or advertise the routes .<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Line 159: Overview<o:p></o:p></p>
<p class="MsoPlainText">> Is it possible to enabled BGP only on private IP address ?
<o:p></o:p></p>
<p class="MsoPlainText">With the RoutingInstance entity, you put together:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">1. Which peers you want to connect<o:p></o:p></p>
<p class="MsoPlainText">2. Which networks are involved<o:p></o:p></p>
<p class="MsoPlainText">3. Whether to enable/disable discovery AND advertise of routes.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Also, you will be able to add advertise routes manually.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">So theoretically, you will be able to advertise a private IP address, although I can not see the use case of this.<o:p></o:p></p>
