- Have you wondered 'how does #vPC work?' This video is for you!
vPC is a way of adding layer-2 resiliency to the data centre.
This video explains vPC, by examining the role of the peer-link and keep-alive link, the way traffic flows, and vPC failure scenarios.
Whether you're a network engineer or looking for fundamentals, this video will help you.
Also useful for CCNA Data Center, CCNP Data Center, and CCIE #DataCenter
Part 1: How vPC Works - vPC adds redundancy to the data centre, while avoiding the older technologies like spanning-tree. See how it fits into your solution, and parts under the hood
• Nexus vPC | How vPC works
Part 2: vPC Configuration - Now you know how vPC works, you can start configuring. See how it's done by watching live config on real Nexus switches

Part 3: Routing over vPC - Be careful! There are pitfalls when running routing protocols over vPC! I fell into one of these myself. See how you can avoid this

As a young network engineer desperate to keep up with far experienced colleagues and rapid new technologies, I can only say thank you and keep up the good work.
Visual explanatory > abstract thinking
You're very welcome. It's good to hear that the videos are working :)
Same here! This video was kind of a life saver. Nexus Switches never got taught in our school and there's no way you can practice them on Packet Tracer. Really good video ! Thanks
Damn, pardon my french, but I think I found a hidden gem among thousands of networking channels on YT. I've seen your vxlan series and now this one, 100% perfection. From a Net Admin to another, many thanks.
You're welcome! Glad to share the experience around
where is the french?
7:49 the menacing ransom note style omg thats brilliant. I am definitely not forgetting these lessons the way you're cleverly framing and demonstrating them. nicely done!
You videos are so amazingly professional I feel like deleting any videos I ever put up. Great job
One of the best explanation I have come across. Complex topic explained so clearly. Like the animation used. Thank you for this video :)
Great approach to the subject - if someone is a visual learner, all it takes is watching your video twice and it gets into the blood! Cheers mate!
so good to hear that you like the videos, thanks!
Awesome explanation of how VPC works!

Man this is a great explanation. You made me understand vpc in an clear way. Kudos
A clear explanation was the goal, so I'm glad it worked out :)
Appreciate your efforts. Your videos are short, but covers all the major components of the topic; nevertheless they are far easier to understand than many other commercial stuffs out there.
Thanks Prashant,
I find shorter is better in many cases.
I Loved the way you described vPC . really appreciate your hard work !!
I really appreciate your comment! Thanks Azhar!
Sound effects at 12:13 made me lol. Another good explainer!
hahaha! I need to do more things like that 😆
you make learning very fun. thanks
I am new to vPC, Well Explained!!
THis kind of video for VDC and OTV will be a boon to humanity. You are awesome thanks a lot for breaking down in the best way... kudos..
Glad you found it useful.
Thanks for the feedback. I don't think I'm in a good position to cover VDC or OTV at this time. I don't have enough experience with them to do them justice. Maybe one day :)
great job, one thing, that scratching sound to simulate the writing, was driving me nuts, I couldn't complete the video, but the content and the speed is perfect, thanks
Yeah, I've since stopped using it
Just needed to do a quick review on some technologies all I can say is thank you, your video is top notch 👍👍👍
Thank you very much!
Fantastic video! I understand the concepts so much better now!
I love all of your videos, clear and right to the point. I'll stick by for eternity.
Thank you so much :)
Awesome, thank you!
outstanding video. better than some other paid video series! you just got another subscriber!
As I mentioned in the video, let me know if you're interested in routing over vPC
Network Direction Yes please.
Thanks for the feedback! I'm a bit slow at creating videos, but I'll get it done :)
Yes please.

Thanks Rajib, I appreciate the comment
Very useful.
Although this video was made over 4 years ago, it is still the best video explain vPC.
Thanks!
awesome man keep up the work got clear insight on vPC
Thanks Sandeep, I'll try to keep it up.
My current project is a series on how VxLAN works, including configuration on Nexus
Simple and quick explanation.

Clear explanation. Thanks.
You're welcome!
Really great explanation and examples which u share it’s awesome
Thanks! You're welcome!
Your visuals really help, thanks for the video! When you see a port-channel between peers in some topologies, is this what contains the keep alive and peer link? Or are they meant to be configured separately?
Good question!
They need to be physically separate.
A layer2 link (ideally a port channel with trunking) for the peer link, and a routed link as the keep alive
They need to be separate, as a failure in one shouldn’t affect the other
Excellent presentation
Great job !!

Great Video!
Thanks Rohit, I'm glad you like the channel!
well done... i like the animations...
Thanks,
It took me a long time to do the animations (I'm a network guy, not an animation guy), so I'm glad you liked it
nice explaination
Excellent 🙏
Super best, thanks..!!
You're welcome!
Great explanation, what software do you use for your presentation?
I use a few different things. Fusion for the 3d parts, powerpoint for the 2d animations, and Shotcut for timeline editing
New sub! Am here coz someone dared to answer this topic. Thanks 😊
Thanks! It was a tricky one to cover, so I'm glad it's helpful
This video is amazing
Thanks, glad you like it!
Thanks for your great explanation. could you please have video about vpc with HSRP.
That's a good idea.
For now, there is an article I wrote on this topic that you may like:

good ingormation easly understand
Thanks, I'm glad it helps
very nice, thank sharing~~~ Good!!!!
Thanks, glad you like it
I am new to vPC, thanks to your well detailed presented Video, i am well aware of the basics now, thank you.:
One Question, the keepalive or the peer link only monitors the link between the peers or the peer switches themselves, but not the member link of each vPC peer switches.
In scenario where the peer link goes down, as you mentioned, the secondary switch disable the member port, but WHAT IF the member port of the primary switch goes down too, Now what, how will the secondary switch know of that.
2nd Scenario, in case where 1st peer link then the keep alive link goes down, the secondary switch will disable the member port, bot for how long, what if the primary switch goes down too later, how will the secondary switch know. will this need a admin intervention too or is there a workaround designed for same.
As I understand it, in scenario 1, the secondary will shut down the member ports as you say. If one of the member ports then goes down on the primary, the secondary won't do anything about it. It keeps its ports down until the peer-link is fixed. It does this for (1) loop prevention, and (2) because it has no way of knowing about the failure on the primary (as the peer-link is down)
For your second scenario...
If the peer and keep alive links are down, the secondary switch cannot know the state of the primary. There are no links the switches can use to communicate this information.
This would be a rare scenario, but it is definitely where we need admin intervention, perhaps to manually swap the roles, or ideally, fix the peer-link and keepalive
excellent video
Thank you very much!
really good explanation
Glad it helped!
Thanks , How configuration EBGP from VPC to VSS switch , should we use L2 link or L3 link ?should we have additional link between vpc switch ?
Using Layer 3 routed ports is preferred for peering.
eBGP can use multi hop anyway, so you shouldn’t have the same problems that IGPs have
