Virtual Port Channels
vPC is used in the data centre to provide active/active links, and help eliminate spanning tree
Following on from the vPC article, we look deeper into the peer-link, keepalive, duplicate frames, failure scenarios, and other advanced concepts
vPC's can do more than connect network devices... They can connect other Nexus vPC switches! This article shows how to configure a back to back vPC (or multilayer vPC, or double-sided vpc)
FabricPath is one way of eliminating spanning-tree in the data centre. It provides a robust spine/leaf architecture, and is complimented by vPC
vPC with HSRP, VRRP
vPC and HSRP work well together. There are some differences to the way it's used, though. This article looks at how to implement HSRP and VRRP with vPC.
I started Network Direction in 2008 as a way to reinforce what I've learned, and to share what I've learned with others. It wasn't long before I was posting articles on networking, Linux, Windows, and general Systems Administration.
Over the years my attention got diverted, and the site didn't get updated as often as I would have liked. I also found the content to be too general and unorganized, covering too many different areas of IT.
For this reason, in 2016 the site was redesigned into the site you see now. It is much more organised, and focuses more on networking, and less on general systems administration.
I hope the resources found on this site are of some benefit to you. If you find anything interesting, please share with others. Please feel free to contact me with ideas, suggestions, or comments.
