 DMVPN Hub

+Overview
+********
+
+General information can be found in the :ref:`vpn-dmvpn` chapter.
+
+This blueprint uses VyOS as the DMVPN Hub and Cisco (7206VXR) as multiple
+spokes. The lab was build using :abbr:`EVE-NG (Emulated Virtual Environment NG)`.
+
+.. figure:: /_static/images/blueprint-dmvpn.png
+   :alt: DMVPN network
+
+Each node (Hub and Spoke) uses an IP address from the network 172.16.253.128/29.
+
+The below referenced IP address `192.0.2.1` is used as example address
+representing a global unicast address under which the HUB can be contacted by
+each and every individual spoke.

-This example is verified with a Cisco 2811 platform running IOS 15.1(4)M9 and
-VyOS 1.1.7 (helium) up to VyOS 1.2 (Crux).
+The individual spoke configurations only differ in the local IP address on the
+``tun10`` interface. See the above diagram for the individual IP addresses.
