+## Description
+The lab is a multi-node topology that consists of two racks with two dual-homed servers connected with a leaf-spine network.
+
+
+<div class="mxgraph" style="max-width:100%;border:1px solid transparent;margin:0 auto; display:block;" data-mxgraph="{&quot;page&quot;:1,&quot;zoom&quot;:1.5,&quot;highlight&quot;:&quot;#0000ff&quot;,&quot;nav&quot;:true,&quot;check-visible-state&quot;:true,&quot;resize&quot;:true,&quot;url&quot;:&quot;https://raw.githubusercontent.com/srl-labs/containerlab/diagrams/cvx.drawio&quot;}"></div>
+
+## Use cases
+This is a "Cumulus In The Cloud" topology designed to demonstrate some of the advanced features of Cumulus Linux. It is based on the [original CITC demo environment](https://www.nvidia.com/en-gb/networking/network-simulation/) with the only exception being the reduced number of spine switches (2 instead of 4). The topology can be spun up fully provisioned with the following two configuration options:
+
+1. [EVPN Multi-Homing](topo-mh) -- an EVPN-VXLAN environment with layer 2 extension, layer 3 VXLAN routing and VRFs for multi-tenancy that uses a multicast underlay for VXLAN packet replication and does not use MLAG or CLAG.
+2. [EVPN Symmetric Mode](topo-mlag) -- an EVPN-VXLAN environment with layer 2 extension, layer 3 VXLAN routing, VRFs for multi-tenancy and MLAG/CLAG for server multi-homing.
+
+## Instructions
+
+Each configuration option is provided in its own configuration file -- [`symm-mh.yml`](topo-mh) or [`symm-mlag.yml`](topo-mlag). See [instructions](/lab-examples/lab-examples/#how-to-deploy-a-lab-from-the-lab-catalog) for how to deploy a topology. 
+
+Once up, each node can be accessed via ssh using its hostname (automatically populated in your `/etc/hosts` file) and the default credentials `root/root`:
+
+```
+ssh root@clab-citc-leaf01
+Warning: Permanently added 'clab-citc-leaf01,192.168.223.3' (ECDSA) to the list of known hosts.

+
+!!!note
+    Due to the different boot order inside a container, BGPd may come up stuck waiting for IPv6 LLA of the peer. This issue only appears on the initial boot and can be fixed with the `vtysh -c 'clear ip bgp *` command.

+For nodes that come up with `sshd` enabled, the following lines can be added to `~/.ssh/config` file to simplify access and prevent future ssh key warnings:

 As mentioned in the introduction of this article, the lab examples shipped with containerlab explain the features containerlab offers. The comprehensive lab examples are not part of containerlab installation as we want the community to own their work.
