DMVPN Explained | VPN Tunnels Part 4
GRE is fantastic, but lacks the scalability needed for a large network. Point to point tunnels require a lot of effort, and are complex to maintain and troubleshoot.

DMVPN on the other hand, does not need point to point tunnels. It uses multipoint GRE to lower the overhead. Additionally, it will dynamically allow spoke routers to register themselves with the hub routers.

This relies heavily on NHRP (Next Hop Resolution Protocol). NHRP finds efficient paths through NBMA (Non-Broadcast Multi-Access) networks. It works with DMVPN by controlling the registration process.

Over time, DMVPN has been improved on. Phase-1 is the original type of DMVPN. It’s simpler to understand, so we’re starting with it here in this video.

In the next video, we’re looking at Phase-2 and Phase-3, and how they are used to improve DMVPN.
