Ask the Expert: Understanding OTV (Overlay Transport Virtualization) on Nexus 7K

08-15-2014 04:15 PM PST thru 08-29-2014 11:15 AM PST

 

Welcome to the Cisco Support Community Ask the Expert conversation.  This is an opportunity to learn and ask questions about Overlay Transport Virtualization (OTV)

Overlay Transport Virtualization (OTV) on the N7K is an industry-first technology that significantly simplifies extending Layer 2 applications across distributed data centers. You can now deploy Data Center Interconnect (DCI) between sites without changing or reconfiguring your existing network design.

OTV is an IP-based functionality that has been designed from the ground up to provide Layer 2 extension capabilities over any transport infrastructure: Layer 2 based, Layer 3 based, IP switched, label switched, and so on. The only requirement from the transport infrastructure is providing IP connectivity between remote data center sites. In addition, OTV provides an overlay that enables Layer 2 connectivity between separate Layer 2 domains while keeping these domains independent and preserving the fault-isolation, resiliency, and load-balancing benefits of an IP-based interconnection.
