This past week Mark Snow and I completed the first of three of our CCIE Data Center Live Online Bootcamps – Nexus Switching. This class focused on the core Layer 2 Switching and Layer 3 Routing features of Nexus NX-OS on the 7000, 5500, and 2000 platforms, and the Data Center specific applications of the platforms with technologies such as vPC, FabricPath, and OTV, just to name a few. The videos from class are now in post-processing, and will be available both for download and in streaming format, both of which have cross platform support (Desktop, iPhone/iPad, Android, Windows phone, etc.) Also as usual our videos are DRM free, so once you purchase them they are yours to do with as you please.

All Access Pass subscribers will get access to the videos in streaming format for no additional fee, and can also purchase the download version at a discounted rate. The download version can be purchased standalone here for people who are not AAP subscribers. Our next two classes, CCIE Data Center Storage and CCIE Data Center Unified Computing are coming up at the end of September and October respectively. All AAP subscribers can attend the live online classes for free, while anyone who want to purchase the download in advance also gets access to attend these classes.

Below are some excerpts from the class relating to the new FabricPath technology. FabricPath is a new alternative to running Spanning-Tree Protocol in the Layer 2 DC Core, and is a pre-standard version of the TRansparent Interconnection of Lots of Links (TRILL) feature. The videos below cover the underlying theory of FabricPath, it’s basic configuration, it’s more advanced configurations and verifications, and its integration with Virtual Port Channels (vPCs) with the vPC+ feature.

Recently, there were discussions going around about Cisco’s new datacenter technology – Overlay Transport Virtualization (OTV), implemented in Nexus 7k data-center switches (limited demo deployments only). The purpose of this technology is connecting separated data-center islands over a convenient packet switched network. It is said that OTV is a better solution compared to well-known VPLS, or any other Layer 2 VPN technology. In this post we are going to give a brief comparison of two technologies and see what benefits OTV may actually bring to data-centers.

VPLS Overview

We are going to give a rather condensed overview of VPLS functionality here, just to have a baseline to compare OTV with. A reader is assumed to have solid understanding or MPLS and Layer 2 VPNs, as technology fundamentals are not described here.
