+# VXLAN Router-on-a-Stick
+
+This directory contains *netlab* topology file for a VXLAN router-on-a-stick scenario doing VXLAN-to-VXLAN routing between a set of VXLAN-enabled VLAN interfaces.
+
+![VXLAN router-on-a-stick topology](netlab-vxlan-router-stick.png)
+
+After starting the lab, *h1* should be able to ping *h2*.
+
+## Changing Device Types
+
+This topology can be used with all network devices supporting VLAN configuration module and all virtualization providers supported by *netlab*:
+
+* To change all devices in the topology (apart from Linux hosts), use the `-d xxx` CLI argument
+* To change the switch device type, use `-s groups.switches.device=xxx` CLI argument
+* To change the router device type, use `-s groups.routers.device=xxx` CLI argument
+* To change the virtualization provider, use `-p` CLI argument.
+
+For example, to start the lab with Cumulus VX devices, use:
+
+```
+netlab up -d cumulus
+```
