Nexus vPC | How vPC works

[@volfram1]

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?

[@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!

[@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!

[@NetworkDirection]

As I mentioned in the video, let me know if you're interested in routing over vPC

[@CiscoPhipse]

Network Direction Yes please.

[@NetworkDirection]

Thanks for the feedback! I'm a bit slow at creating videos, but I'll get it done :)

[@baskaran98]

Yes please.

[@NetworkDirection]

Routing over vPC video is here: kzbin.info/www/bejne/gYHWn3xsnZaFf9U

[@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 :)

[@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

[@waletechniques]

Just needed to do a quick review on some technologies all I can say is thank you, your video is top notch 👍👍👍

[@NetworkDirection]

Thank you very much!

[@aidaandaz3803]

Very useful. Although this video was made over 4 years ago, it is still the best video explain vPC.

[@NetworkDirection]

Thanks!

[@simonbingham3174]

You videos are so amazingly professional I feel like deleting any videos I ever put up. Great job

[@ttscha]

Man this is a great explanation. You made me understand vpc in an clear way. Kudos

[@NetworkDirection]

A clear explanation was the goal, so I'm glad it worked out :)

[@prashantbangera4000]

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.

[@NetworkDirection]

Thanks Prashant, I find shorter is better in many cases.

[@kanesalingamtharmeswaran5809]

Wow brief still well organized explanation. Thank you...

[@sandeepch7874]

awesome man keep up the work got clear insight on vPC

[@NetworkDirection]

Thanks Sandeep, I'll try to keep it up. My current project is a series on how VxLAN works, including configuration on Nexus

[@satyapramod8762]

easily understandable. Thanks for the video.

[@abdumka]

@2:30 what are examples for control plane traffic in this case?

[@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?

[@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

[@veerakumardevireddy2884]

Excellent presentation 👍

[@NetworkDirection]

Thank you

[@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

[@tejasgawad315]

I really liked the way you explained. Thanks for the awesome video.

[@b0ys0l09]

To connect the vPC to L3 switches (hsrp) for VLAN routing, are extra configuration required?

[@NetworkDirection]

Do you mean adding HSRP to the switches that are also on vPC? This works quite well. I haven't done it in a while, but from memory it's just regular HSRP config

[@b0ys0l09]

@@NetworkDirection Thank you for replying. I wish I could share the topology diagram. Current topology is 2 Catalyst SW configure with HSRP and are in Active/Standby with VIP addresses as default gateways for multiple VLANs. Between the Catalyst there is a L2 trunk connection. And what I meant was to connect the newly configured vPC domain to the 2 Catalyst switches. Active Catalyst connected to vPC peer1 and Standby Catalyst connected to vPC peer2. Will the above work or do I have to configure additional settings? Thank you in advance.

[@NetworkDirection]

@@b0ys0l09 I may have misunderstood, but I didn't think vPC was available on the Catalyst platform. Only the Nexus?

[@b0ys0l09]

@@NetworkDirection the vPC peers both are nexus switches and the plan was to connect them to the Active/Standby catalyst switches.

[@NetworkDirection]

@@b0ys0l09 Yeah, that should be fine. You will probably find increased traffic on the peer link.

[@justinboss4131]

Great video... love the animation

[@jaykay4769]

Love the animation they are awesome

[@jackyappu]

really good explanation

[@NetworkDirection]

Glad it helped!

[@lukasvenuticoelho9261]

Muito bom, excelente e aprofundada explicação. Obrigado.

[@NetworkDirection]

de nada

[@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

[@iyobhambisa3752]

Thanks, it's very understandable

[@creaple399]

I didn't understand one thing and will appreciate if someone explain it to me. In 12:10 case when primary switch turns off and in 12:50 when keep alive connection breaks I thought for Secondary switch this cases are the same and result will be also same

[@chandu0771]

good ingormation easly understand

[@NetworkDirection]

Thanks, I'm glad it helps

[@techguy7961]

thanks so simple explain complex topic

[@theunderhook9913]

Just amazing! Subscribed!

[@NetworkDirection]

Thanks Pav!

[@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.

[@aswath7]

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

[@ostinlt12]

Absolutely excellent video! Very informative. thanks.

[@NetworkDirection]

Glad you like it, thanks

[@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

[@josesaenz7453]

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

[@tigreshs]

[@kulvindersinghvlogs]

nice explaination

[@josecarlosglz.barron9314]

thanks, it´s very usefull

[@AlexCruz-mv1gj]

So the keep alive link doesn't need to be multiple links, like in port/etherchannel?

[@ronimulya9414]

Great explanation sir, thankyou!

[@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

[@SurajGupta-tz5qy]

Nice content and Very nice explanation .. Keep up the good work .
