How To Configure Dynamic Routing Over An L2TP Tunnel

Introduction

This How To Note shows an example of using a dynamic routing protocol over an L2TP tunnel.

Running dynamic routing protocols over a secure Internet connection can be a complex issue, with the possibility of intermittent connections causing routing problems.

OSPF (or BGP) are more connection-oriented than RIP and therefore are more susceptible to problems caused by intermittent loss of connection between 'neighbours'. A neighbour that may bounce up and down can cause havoc to the correct propagation of OSPF routing information for a network.

The following example scenario is for setting up RIP over an L2TP tunnel. RIP is simpler and has less overhead and control, so it provides a more robust setup as a dynamic routing protocol over an L2TP tunnel.
