Configuring DMVPN Phase 3 w/ EIGRP

In this blogtorial we will configure DMVPN Phase 3 and run EIGRP over the tunnel. After reading this blogtorial, I hope that you will have a clear understanding of DMVPN Phase 3 and how it interacts with EIGRP. If you need a primer on DMVPN Phase 1 and Phase 2, please see my DMVPN blogtorials.

Here is the topology.

Configuring DMVPN Phase 2 w/ EIGRP

In this blogtorial we will configure DMVPN Phase 2 and configure EIGRP over the DMVPN tunnel. Over the past few blogtorials we've been concentrating on how to configure DMVPN Phase 1 and routing protocols over DMVPN Phase 1. One of the key disadvantage of Phase 1 is that all spoke to spoke traffic must pass through the HUB which is a bit inefficient. DMVPN Phase 2 improves on DMVPN Phase 1 by allowing for on-demand dynamic spoke to spoke tunnels based on traffic patterns.

Here is our topology.
