<Please login to see the content>

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.

Both R1, R2 on physical diagram, wouldn't it be another connection go to the SW, would it?

R1 and R2 has Fa0/0 that connects to internet and Fa0/1 that connects to inside LAN as shown in logical topology..
