already set to ''. Really, in the article just need to make sure your bridge mappings are set to both interfaces where each interface represents the external networks.<br>
</p>
<p><br>
</p>
<p>As far as how that data gets back to one data center rack, really i'ts tunneling, i.e. GRE/VXLAN, in the context of self-service networks.<br>

<p class="MsoNormal">I was wondering as to how to host multiple subnets on one data center rack.</p>
<p class="MsoNormal"> <br>
</p>
<p class="MsoNormal">Let me explain:<br>
</p>
<p class="MsoNormal"> <br>
</p>
<p class="MsoNormal">I have a virtual network function, say vRouter.<br>
</p>
<p class="MsoNormal">I have two subnets in the external network 192.168.x.x and 192.178.x.x, then from the edge router how can I get it to go to different compute nodes..</p>
<p class="MsoNormal">What is the mechanism in OpenStack to do this? Like a tunnel or something?</p>
<p class="MsoNormal"> <br>
</p>
<p class="MsoNormal">How can I achieve the above in my data center with OpenStack?</p>
