Nexus vPC | How vPC works

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

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

[@NetworkDirection]

You're very welcome. It's good to hear that the videos are working :)

[@prateeksachdeva2185]

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

[@diaphanoux]

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.

[@NetworkDirection]

You're welcome! Glad to share the experience around

[@muzzammilahmed238]

where is the french?

[@fannz66]

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!

[@NetworkDirection]

so good to hear that you like the videos, thanks!

[@MegaElecman]

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

[@NetworkDirection]

Yeah, I've since stopped using it

[@brenly__2247]

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!

[@vikas9358]

One of the best explanation I have come across. Complex topic explained so clearly. Like the animation used. Thank you for this video :)

[@lohrasppithawala6616]

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..

[@NetworkDirection]

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 :)

[@bedevere007]

you make learning very fun. thanks

[@cameronpaulk]

Sound effects at 12:13 made me lol. Another good explainer!

[@shabbirmandviwala5075]

Excellent presentation of Video .You make the concept so easy to understand. Yes will be interested in routing over vPC

[@NetworkDirection]

Thanks Shabbir Good news! I've already done the routing over vPC video. Here it is: kzbin.info/www/bejne/gYHWn3xsnZaFf9U

[@shaileshmsurathkal8285]

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.

[@NetworkDirection]

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)

[@NetworkDirection]

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

[@theruggedboy7958]

very easy to understand. Thank you very much.

[@NetworkDirection]

Glad you like it, thanks!

thanks so simple explain complex topic

[@dipan246]

Superb and best explanation...

[@NetworkDirection]

Thanks!

[@shawn_8888]

Great explanation, very easy to understand. Can you make videos for >> VSS, VRF, OTV?

[@NetworkDirection]

Thanks Ken! VRF videos are in production now. They’ll be a fast paced 4-part series

[@shawn_8888]

Thats awesome, will you also make VSS and OTV?

[@NetworkDirection]

Probably not for a while at least. I don’t feel that I know these technologies well enough at this time. Possibly some time in the future, but it wouldn’t be soon, sorry.

[@shawn_8888]

Its okay no worries, thx a lot anyways, keep up the good work.

[@mitpatel4268]

@12:34 Can I please be informed why there would be no issues if keep-alive link fails but peer link is fine? Do we mean to say that peer link will indicate to the two switches that another switch is alive? If yes, what is the use of having the keep-alive link at all if the peer link already does this job? Am i missing something?

[@justinboss4131]

Great video... love the animation

[@javadh7966]

Thanks for your great explanation. could you please have video about vpc with HSRP.

[@NetworkDirection]

That's a good idea. For now, there is an article I wrote on this topic that you may like: networkdirection.net/vPC+with+HSRP%2C+VRRP

[@josesaenz7453]

Excelente video, explicacion y animacion que deja claro el concepto. Gracias

[@musalyh]

Thanks for sharing a nice video. I have one question. If configure VPC, usually only the VPC primary switch will receive/forward frames??

[@NetworkDirection]

No, as I understand it, they both can forward frames

[@aswath7]

Got cleared about VPC. Do you have any video about how VPC works with MAC pinning

[@lekha7179]

New sub! Am here coz someone dared to answer this topic. Thanks 😊

[@NetworkDirection]

Thanks! It was a tricky one to cover, so I'm glad it's helpful

[@c333ton]

[@Ccieordie_arteq]

well done... i like the animations...

[@NetworkDirection]

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

[@sebastiantucker2219]

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?

[@NetworkDirection]

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

[@rajmane313]

Excellent 🙏

[@dany1669]

great job! Thank you!

[@NetworkDirection]

You're welcome!

[@adamyahya4638]

Is there any way for the switch to deny traffic going out across the peer-link if it's destined to only go out of port-member's only? Seems like you're just making extra work for the switch to process the traffic and send it out of the peer-link only for it to be dropped

[@NetworkDirection]

I think that's handled in the ASIC, and may be platform specific. So as far as I'm aware, there's nothing you can configure

[@jackyappu]

really good explanation

[@NetworkDirection]

Glad it helped!
