redundancy

The video demonstrates another method of achieving redundancy in your DMVPN deployment using NHS cluster and recovery backup feature. We look at how routing and EIGRP neighbor adjacency changes when a spoke registers to one or more NHS at a time in the same cluster, and observe the failover behavior. This feature provides a good compromise between failover time and routing simplicity.

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.
