An example scenario for RIP over L2TP

Our example uses two office sites that are connected via a WAN connection over the Internet using an L2TP tunnel for security.

The setup (shown below) shows the 'Central office' and 'Remote office' routers connected, in this case, back to back via their Ethernet interfaces (this would likely be the remote WAN connection across the Internet, with perhaps static IP assignment from the ISPs).
