VXLAN with BGP EVPN Training | 14 Hours | EVE-NG Labs in Hindi and English | BridgeWhy

  • Learn how to make scalable datacenter using one of the most simple concept i.e. VXLAN with BGP-EVN

Created by - Vishnu Dutt

  • English and Hindi

About the course

You picked this topic because data center jobs ask for VXLAN with BGP-EVPN, and the older tutorials feel like a wall of commands without a clear reason. People learn the configuration, copy the lines, and then freeze the moment something breaks in production. The reason is simple. Without a clear mental model of underlay, overlay, MAC learning, and the role of the BGP control plane, every troubleshooting ticket feels like a puzzle. The instructor for this course, Vishnu Dutt, has 19+ years at Cisco and has trained 15000+ learners across 100+ countries. The teaching style is built on the why first principle: you understand the mind of the engineer who designed the protocol, and then the configuration becomes obvious.

In 12 hours you move from the original VLAN problem all the way to a full working VXLAN fabric with BGP-EVPN, every step built on EVE-NG. Layer 2 and Layer 3 packet walk are drawn on the whiteboard for every scenario, so you can see exactly what happens to a frame the moment it enters a leaf switch, how the VXLAN header is wrapped on top, how the spine carries it, and how the remote leaf strips the header and forwards the original frame. This level of packet walk is what separates a person who can pass the exam from a person who can fix a real outage.

Why both languages in one package

Most learners are comfortable in one language but reach for the other when the topic becomes technical. A Hindi speaker may search "VXLAN kya hai" first but then read Cisco documentation in English. An English speaker may want a Hindi recap before a job interview to lock the concept in memory. This package gives you both versions of the same training, taught by the same instructor, so language is never the bottleneck. You pay once and you study in the language that fits the moment.

Switching Fundamentals is also bundled inside this package without extra cost. The reason is simple. You cannot build a strong VXLAN base without a solid Layer 2 understanding, and we would rather give you that base than send you somewhere else for it. If you want to refresh the foundation first, please see Switching Fundamentals.

### What makes this VXLAN training different

Three things set this course apart. First, the why is always shown before the how. Lesson 1 starts not with a VXLAN header diagram but with the limits of traditional VLAN design and the new demands of multi tenant data centers. Once you feel the problem, the VXLAN solution makes sense in minutes instead of weeks. Second, the BGP-EVPN control plane is not bolted on as an afterthought. The course first walks the older Flood and Learn method, shows the waste it creates, and then introduces BGP-EVPN as the answer. You do not just learn the new way. You understand why the new way exists. Third, every lesson ends in a working lab on EVE-NG. You see the configuration on real network operating systems and you watch the packet capture confirm the theory.

Who this course is for

This course is built for network engineers preparing for CCNP Data Center, DCACI or DCCOR, for engineers moving into a data center role from a campus background, for CCIE aspirants who want a clean reference for VXLAN with BGP-EVPN, and for anyone who has tried to learn VXLAN from scattered material and given up. If you are still building your routing base, please pair this course with Routing Fundamentals and BGP from Scratch. If your CCNA is not done yet, please start with CCNA for Know Nothing Learner or the Hindi version, Be Job Ready in Computer Networking.

What you receive when you buy the package

You receive the full Hindi version, the full English version, the bundled Switching Fundamentals course, all EVE-NG lab files, and a completion certificate from BridgeWhy when you finish. After this course, the natural next steps are Network Automation from Scratch and SD-WAN from Scratch. If you want to lock in your interview readiness, Interview Preparation Series is a strong follow up.

For pricing and access duration, please review the Lifetime Access.

What you will learn


Lesson 1: Why behind VXLAN with BGP EVPN
Every data center engineer eventually meets a 4096 VLAN ceiling, a multi tenant separation request, or a Layer 2 stretch requirement that traditional VLAN simply cannot serve. This lesson sets the stage by showing the exact limits of the older design and the new pressure from cloud workloads. By the end you understand why VXLAN was invented, why a separate control plane was added later, and what BGP-EVPN brings to the table.

Lesson 2: Underlay and Overlay
The biggest source of confusion in VXLAN is the layered model. Once you see that the physical IP network (underlay) is just a transport, and that the tenant network (overlay) is a logical Layer 2 built on top, every other concept falls into place. This lesson builds that mental model with diagrams, then walks an end to end packet so you can see both layers in action.

Lesson 3: MTU Considerations in Underlay
A perfectly working IP underlay can still break VXLAN. The reason is the extra bytes that VXLAN adds to every frame. Standard 1500 byte MTU causes silent drops or fragmentation. This lesson shows exactly why jumbo MTU is required, where to set it, and how to verify that the path supports the new size.

Lesson 4: BUM Traffic handling in VXLAN
Broadcast, Unknown unicast and Multicast traffic must still reach every host inside a VNI. In a pure IP fabric there is no Layer 2 broadcast, so the design needs a workaround. This lesson explains the two main methods, multicast underlay and Ingress Replication, and helps you pick which one fits which deployment.

Lesson 5: Let us build Underlay of VXLAN
Theory without practice fades inside a week. In this lesson you open EVE-NG and configure the spine and leaf devices with IP routing so the underlay is ready to carry VXLAN frames. You see the routing tables, the loopback design, and the reason every choice was made.

Lesson 6: Flood and Learn in VXLAN
The first generation of VXLAN had no control plane. Switches discovered MAC addresses by flooding everything to everywhere, exactly like a hub. This lesson walks the full Flood and Learn frame path so you can see the waste, and so the upgrade to BGP-EVPN feels earned rather than mysterious.

Lesson 7: Why behind BGP-EVPN
Flooding does not scale. The industry already had a proven protocol for distributing reachability information across many devices, and that protocol is BGP. Adding the EVPN address family lets BGP carry MAC and IP information just like it carries IP prefixes. This lesson explains that design decision and prepares you for the route types in the next lesson. For a deeper BGP base, please see [BGP from Scratch](https://www.bridgewhy.com/courses/BGP-from-Scratch-65489f52e4b07165bdcdddaa).

Lesson 8: VXLAN Control Plane: BGP EVPN
EVPN route types look intimidating until you see what each one solves. Route Type 2 carries MAC and IP. Route Type 3 handles BUM membership. Route Type 5 carries Layer 3 prefixes between VRFs. This lesson decodes each route type with packet captures and shows how the control plane keeps every leaf in sync.

Lesson 9: Inter and Intra-VXLAN Configuration
A real fabric must support both Layer 2 stretch within a single VNI and Layer 3 routing between different VNIs. Without both, the design is incomplete. This lesson configures Intra VXLAN bridging and Inter VXLAN routing on EVE-NG, with a clean packet walk for each case so you can explain the behavior in an interview.

Lesson 10: Enhancements due to BGP VXLAN
BGP-EVPN unlocks features that pure Flood and Learn cannot offer. ARP suppression saves uplink bandwidth. MAC mobility supports virtual machine moves across leafs. Anycast gateway lets every leaf act as the default gateway so workloads move without losing sessions. This lesson covers each enhancement with the why behind it.

Lesson 11: External Connectivity
A VXLAN fabric is useless if it cannot reach the outside world. The Border Leaf is the bridge between the fabric and the WAN, the internet, or another data center. This lesson explains the role of the Border Leaf, the design choices, and the configuration that joins the inside of the fabric to everything outside.

Here is know your instructor "I spent 18 years building computer networks at Cisco. But honestly, I am more curious than technical. I read. I listen to podcasts. I follow finance, health, and whatever new trend is quietly changing the world before most people notice. That curiosity is why I teach the way I do. I never start with "how." I always start with "why." Because if you understand why something exists, the how becomes easy. Right now, that curiosity brought me here. To help people understand what AI is really doing to jobs and careers. Before it is too late."

Frequently asked Questions


What does this course actually teach?

The course takes you from the original VLAN scaling problem to a full working VXLAN fabric with BGP-EVPN. In 12 hours you cover underlay, overlay, MTU, BUM traffic, Flood and Learn, EVPN route types, Inter and Intra VXLAN routing, ARP suppression, anycast gateway and external connectivity. Every concept is shown on whiteboard and then built on EVE-NG.

Is the Layer 2 and Layer 3 packet walk done on whiteboard or only on slides?

On whiteboard for every scenario. You see what happens to the frame the moment it enters the leaf, how the VXLAN header is added, how the underlay carries the packet, how BGP-EVPN learned the MAC and IP, and how the remote leaf strips the header and delivers the frame to the destination host.

How deep does the course go into EVPN route types?

Route Type 2 (MAC and MAC plus IP), Route Type 3 (Inclusive Multicast), and Route Type 5 (IP Prefix) are covered with packet captures. You also see how each route type is generated, advertised, and consumed.

Does the course cover both Layer 2 and Layer 3 VXLAN?

Yes. Layer 2 stretch using the same VNI across leafs is covered. Layer 3 routing between different VNIs is covered, including the symmetric IRB design used in most production fabrics.

What underlay protocol is used in the labs?

The labs use a simple IGP based underlay so that the focus stays on VXLAN and BGP-EVPN. You can replace the IGP with your preferred choice and the overlay behavior remains the same.

Are real configurations shown or only theory?

Real configurations on real network operating systems inside EVE-NG. Every lesson ends with you seeing the device output, the BGP table for the EVPN address family, the MAC address table, and the packet capture that confirms the theory.

What should I already know before starting this course?

A solid Layer 2 base. Switching Fundamentals is included free inside this package so you can refresh that base. Comfort with basic IP routing is helpful.

Do I need BGP knowledge before I start?

Not strictly. The course explains the EVPN address family from scratch. If you want to feel completely at home, please review BGP from Scratch first.

Is OSPF or IS-IS required?

You need a working IGP for the underlay. You do not need to be an expert in either. If you want to strengthen your routing base first, please see Routing Fundamentals.

Is CCNA enough as a base?

Yes for most learners. If your CCNA is not done yet, please start with CCNA for Know Nothing Learner in English or Be Job Ready in Computer Networking in Hindi.

Why do you sell both Hindi and English together?

Most learners switch between languages depending on the source they are reading. The package removes the language decision so you can move between the two versions without paying again.

Are the Hindi and English videos the same content?

The technical content is the same. The Hindi version is in Hinglish, which means English script with a Hindi sentence structure and English technical terms.

Can I use both versions in any order?

Yes. Many learners watch the Hindi version first for concept absorption and then watch the English version before interviews to lock the vocabulary.

Will this help me with CCNP Data Center?

Yes. VXLAN with BGP-EVPN is a core topic in CCNP Data Center, DCACI and DCCOR blueprints. The depth of packet walk here goes beyond exam level.

Does this map to the Cisco DCACI exam?

The protocol fundamentals, the EVPN route types, and the configuration patterns align well with DCACI. The course is product neutral on the control plane logic, which is exactly what the exam tests.

Will I receive a certificate?

Yes. A Completion Certificate by BridgeWhy is issued when you finish the course.

Will this course prepare me for VXLAN interview questions?

Yes. The packet walk style of teaching is exactly what senior interviewers test. You can pair this course with the Interview Preparation Series for a complete plan.

Are common interview scenarios covered?

Common scenarios such as ARP suppression, MAC mobility, asymmetric versus symmetric IRB, and Border Leaf design are covered with the reasoning that interviewers expect.

What lab tool is used?

EVE-NG. All demos and labs are built on EVE-NG so you can replicate every topology on your laptop.

Do I need a powerful laptop for EVE-NG?

A modern laptop with at least 16 GB of RAM is recommended. The lab topologies are sized to run on common engineering laptops.

Are the lab files shared?

ase configurations and topology files are shared so you do not lose time on setup.

What are the access options?

Three plans are available: a short term plan, a one year plan, and a lifetime plan. Most learners choose Lifetime Access because VXLAN is a topic engineers return to for every new role. The full plan list is on the BridgeWhy Store.

Can I download the videos?

Videos are streamed inside the BridgeWhy platform. Lab files and notes are downloadable.

Who is teaching this course?

Vishnu Dutt. He has 19+ years at Cisco and has trained 15000+ learners across 100+ countries. You can read more on About Us.

Which course should I take after VXLAN with BGP EVPN?

Network Automation from Scratch is the natural next step because modern data center fabrics are operated through automation. SD-WAN from Scratch is a strong second choice if you want to connect data centers across sites. If you have not yet seen SD-Access, it is free and gives you a parallel view of fabric design in the campus space.
