VXLAN | Part 6 - BGP EVPN Configuration on Nexus 9000

Welcome to part 6, where we follow ip on the real configuration with control plane learning, AKA #BGP #EVPN.

In this training video, continue past the fundamentals with a configuration technical deep dive. This includes VTEPs, ingress replication (AKA head end replication), OSPF in the underlay, VNI’s and encapsulation (tunnels) in the overlay, BGP, VRF’s, Integrated routing and bridging (IRB), ARP suppression, and anycast gateway, all on real Cisco Nexus (NX OS) 9000 switches.

In short, this lab covers how to configure and troubleshoot #VxLAN control plane learning. This also shows how to configure a multi-tenant VxLAN environment using MP-BGP, VRF’s, Route Targets, and Route Distinguishers.

Did you know that VTEPs are not called VTEPs on a Nexus switch? They use a special interface called an NVE. This takes its IP address from a loopback interface.

Part6 took most of the time to understand. Hope there can be more easier way.

[lakhvirdhiman]

Thank you very much for creating this. It gives a quick and wonderful summary.

Fabulous series, concise and to the point. Exactly the right style of presentation, no fluff to wade through and all concepts explained to just the right level of detail with minimum repetition. I'll be referring back to this series a lot in future!

[JoeBee]

Wow. After Part 6 I now know why people goes ACI to overcome this configuration efford. Thanks for this deep look inside.

[vijaypillai]

Great Educational Videos on VXLAN . Clear & Well explained . Thank you.

[patrickwilliams]

Really enjoy how you go through all the configuration for both switches with explanations for the commands. Makes it easy to follow along while configuring it yourself.

[luckyduckimages]

solid description on the VXLAN technology. Many thanks...

[patrickreilly]

We implemented ACI about 2 years ago but having a review on the capabilities is very enlightening. Who possibly thinks up this stuff? Genius
.

Watched all 6 videos, very good work. Have made notes for each video. Can see the hardwork to put these videos together that explain VXLAN un best possible way.

[johngilbert]

Thank you for explaining how Cisco does VXLAN. I had just about understood VMware NSX so this was really useful.
Lots of new terms to use and I'll need to read more to get it straight in my head.

[pandeyajay]

Excellent Video and really simplified explanations !!!!

[alaertevidali]

I agree with Dan Le words: the BEST explanation I see so far about VXLAN. Also generally the best technical video explanation I had the luck to watch. Thanks a Lot!!!!

[rfc]

Excellent video series on VXLAN It just simply hit all the necessary keys to understanding and implementing VXLAN Thank You!!!!.

[anjankumar]

Superb series. Simple but great tutorial. Thank you so much.

[wechecha]

Thanks very much. You broke down the technology I have been fighting with myself to understand. You walked me over the water to cross the pond of VXLAN :-)

[pjstevens]

great series, well explained. best video I've seen on VXLAN, I understand much better after watching this series

[sameerkumar]

Your explanation is crisp and superb. I am learning VxLAN first time and it seems closely related to traditional L2, L3 VLAN with several new added feature such as Anycast and improved MAC/ARP learning. Thanks for your video

[inswingone]

Outstanding series on VXLAN. The depth, width and clarity of topics is outstanding....

[templofuerte]

Pretty good series and a kick start for anyone who is new into VXLANs. Two things worth mentioning. First if you are running a VPC between your Nexus switches you need to add a secondary IP address to your loopback0 interface, the IP is the same for both devices and will be shared if they need to communicate to other nve peers. Your VPC will fail due to consistency reasons otherwise. Second and not so important, show nve peers will have empty output until there is bidirectional traffic.

[bertrand]

It is very helpful and simply described for beginners with VXLAN. I work since two weeks on VXLAN, I thought it was complicated, but with your videos, all will be clear for me in the evening when I watched the VXLAN series videos. Thank you very much ;)
