<h1 id="demo-on-vlab">Demo on VLAB</h1>
<p>Goal of this demo is to show how to use VPCs, attach and peer them and test connectivity between the servers. Examples
are based on the default VLAB topology.</p>
<p>You can find instructions on how to setup VLAB in the <a href="../overview/">Overview</a> and <a href="../running/">Running VLAB</a> sections.</p>
<h2 id="default-topology">Default topology</h2>
<p>The default topology is Spine-Leaf with 2 spines, 2 MCLAG leafs and 1 non-MCLAG leaf.

<p>Let's assume that <code>vpc-1</code> already exists and is attached to <code>server-01</code> (see <a href="#creating-and-attaching-vpcs">Creating and attaching VPCs</a>).
Now we can create <code>vpc-3</code> with the same subnet as <code>vpc-1</code> (but in the different IPv4Namespace) and attach it to the
<code>server-03</code>:</p>

<p>At that point you can setup networking on the <code>server-03</code> same as for <code>server-01</code> and <code>server-02</code> in a previous sections
and see that we have now <code>server-01</code> and <code>server-03</code> with the IP addresses from the same subnets.</p>
