The video shows you how to build a redundant DMVPN network with dual-hub dual-cloud design. The failover capability is provided by routing protocol. With EIGRP chosen for demonstration in this video, we show how to perform a simple tweak in the routing metric to solve potential asymmetrical routing. The video concludes with failover testing and shows that spoke-to-spoke traffic is not interrupted upon a Hub failure.
Topic includes
- Dual-hub dual-cloud DMVPN redundancy
- EIGRP metric adjustment
- DMVPN failover test
Pros
- Complete routing control with two spoke tunnels for spoke inbound traffic
Cons
- Additional spoke tunnel configuration and subnet are required

Can you provide a link to the script you are using? Thanks.
Physical diagram
Both R1, R2 on physical diagram, wouldn't it be another connection go to the SW, would it?
Physical diagram
R1 and R2 has Fa0/0 that connects to internet and Fa0/1 that connects to inside LAN as shown in logical topology..
