About the course

Aap IS-IS Hindi mein seekhna chahte hain, 

aur aapne notice kiya hoga ki online material ki quality thodi kam hai. English mein toh phir bhi kuch mil jaata hai, lekin Hindi mein IS-IS ka proper structured course dhoondhna mushkil hai. Yeh page usi problem ka jawaab hai. Yahaan aapko IS-IS from Scratch ka Hindi only version milega, 8.5 ghante ki full training, 6 lessons mein baanta hua, aur har lesson ki shuruaat "Why" se hoti hai. Kyunki jab tak aap protocol banane wale ke dimaag ko nahi samjhoge, sirf commands yaad karke aap network engineer nahi banoge.


Yeh page sirf Hindi seekhne walon ke liye hai. 

Agar aap dono languages ek saath chahte hain, to IS-IS from Scratch Package recommended hai, kyunki uska price dono alag alag lene se kam hai. Lekin agar aapko Hindi mein hi padhna hai, to yehi course sahi hai, aur iski technical depth English version jaisi hi hai.


IS-IS ki language Hindi mein padhne ka ek badaa fayda hai. 

Technical terms toh English mein hi rahenge (TLV, NSAP, LSP, adjacency, level, DIS), lekin unke peeche ka logic Hindi mein samjhaane par bahut jaldi baith jaata hai. Whiteboarding aur analogies ke saath, jab hum kehte hain "socho, IS-IS ka router area boundary link par rakhta hai, router par nahi", tab yeh baat English mein sunne se zyada saaf ho jaati hai. Yehi wajah hai ki BridgeWhy par 15000+ learners hain, 100+ countries se, aur Hindi speakers ka ek bahut bada hissa hai.


Har lesson ka pattern same hai. 

Pehle whiteboard, phir analogy, phir configuration, phir Wireshark capture. Kyun? Kyunki jab aap Wireshark mein LSP ko byte by byte dekhoge, tab TLV format aapke liye theory nahi rahega, ek reality ban jaayega. Aap kabhi bhoolenge nahi ki IS-IS ke andar kya hota hai.


Instructor Vishnu Dutt ne 19+ saal Cisco mein bitaaye hain. 

Enhone 15000+ learners ko networking sikhaayi hai, 100+ countries mein. Unka teaching style bilkul saaf hai: "Agar aap kisi cheez ka Why nahi samajh sakte, to uska How yaad rakhne ka koi matlab nahi." Yeh course usi philosophy par bana hai.


Lab tools bhi practical hain. 

EVE-NG community edition free hai, Wireshark free hai, aur ek 8 GB RAM ka laptop kaafi hai. Aapko koi mehnga Cisco hardware nahi khareedna hai. Har lesson ki configuration aap apne ghar par reproduce kar sakte hain, aur agar kahin phanse to discussion area mein sawaal pooch sakte hain.


Course khatam karne ke baad natural next steps hain OSPF from Scratch (agar OSPF pehle nahi kiya), BGP from Scratch, phir MPLS from Scratch, aur enterprise transformation ke liye SD-WAN from Scratch. Beginners ke liye Be Job Ready in Computer Networking Hindi mein available hai. Interview ki tayyaari ke liye Interview Preparation Series le lijiye.

Ek chhoti si baat: agar aap pehle teaching style dekhna chahte hain paise kharch karne se pehle, to SD-Access course FREE hai. Ek do lessons dekh lijiye, aur agar aapko lage ki yeh style aapke liye sahi hai, tab hi IS-IS enroll kariye.

What you will learn


Lesson 1: Why Behind IS-IS Routing Protocol
IS-IS aise hi paida nahi hua. Iske peeche ek pura history hai. Yeh protocol OSI world ke liye bana tha, CLNS routing ke liye. Baad mein jab IP jeet gaya, IS-IS ko Integrated IS-IS banake IP ke liye bhi use kiya gaya. Lekin service provider log jo pehle se IS-IS deploy kar chuke the, unhone kabhi migrate nahi kiya, kyunki IS-IS Layer 2 par direct chalta hai aur TLV format use karta hai. Iss lesson mein aap yehi story samjhoge, aur aapko dikhega ki bade ISPs kyun aaj bhi IS-IS use karte hain OSPF ke bajaay.

Lesson 2: TLVs, NSAP aur Link State philosophy
Yahaan link state ka pura concept clear hoga. Har router apne links ki state advertise karta hai, har router baaki sabki advertisements suntaa hai, aur har router ke paas complete topology ka picture hota hai. Phir TLV (Type Length Value) format samjhaayenge. TLV ki wajah se IS-IS koi bhi nayi information carry kar sakta hai bina protocol badle. IPv6 aaya to naya TLV ban gaya. Segment Routing aaya to phir se naya TLV ban gaya. Aur last mein NSAP addressing tod ke samjhaayenge, taaki Area ID, System ID aur NSEL random string na lagen.

Lesson 3: IS-IS Adjacency, LSP aur Area
Do routers milte hi neighbor nahi ban jaate. Pehle IIH (IS-IS Hello) PDU bhejte hain, parameters match karte hain (MTU, level, area, system ID), phir Down se Init aur Init se Up state mein aate hain. Uske baad LSP exchange hota hai, jo router ke sab links ki information carry karta hai. Iss lesson mein aap Area ka concept bhi seekhoge. IS-IS mein router ek hi area mein rehta hai. Boundary link par hoti hai, router par nahi. Yeh OSPF se bilkul alag design hai, aur isi design ki wajah se IS-IS bade networks mein aasaani se scale karta hai.

Lesson 4: Flooding aur Levels in IS-IS
Har link state protocol ke saamne ek problem hoti hai: har router ko sync mein kaise rakhein bina bandwidth waste kiye aur bina loop banaye. IS-IS iska jawaab deta hai CSNP aur PSNP se. CSNP ek complete list hai jo router ke paas hai, aur PSNP specific LSPs ko request ya acknowledge karta hai. Iss lesson mein aap dekhoge, packet by packet, kaise ek stable IS-IS network apna database consistent rakhta hai. Phir Level 1 aur Level 2 ki hierarchy padhoge: Level 1 area ke andar, Level 2 areas ke beech mein, aur Level 1-2 routers bridge ka kaam karte hain. Isi hierarchy ki wajah se IS-IS hazaaron nodes tak scale karta hai.

Lesson 5: Lab Configuration aur Broadcast Network aur Traffic Path
Ab hands on time hai. EVE-NG mein aap Cisco IOL ya CSR images ke saath IS-IS lab banaayenge. NET address assign karenge, interfaces par IS-IS enable karenge, level set karenge, aur adjacencies aati hui dekhenge. Phir purposely galtiyaan karenge: MTU mismatch, area mismatch on Level 1, authentication mismatch. Broadcast segment par DIS (Designated Intermediate System) election hoga aur aap samjhoge ki IS-IS single DIS with pseudonode kyun use karta hai, DR aur BDR jaise OSPF mein hota hai wo kyun nahi. Wireshark mein har PDU capture hoga aur real me dikhega ki bytes mein kya bhara hai.

Lesson 6: Metrics, Redistribution aur Dijkstra Algorithm
Dijkstra algorithm har link state protocol ka engine hai. Iss lesson mein aap Dijkstra ko haath se, ek chhota topology par run karenge, taaki SPF result predict karna aa jaaye. Phir narrow metric (6 bit, sirf 63 tak) aur wide metric (24 bit) ka farak samjhoge, aur kyun har serious IS-IS deployment wide metric style use karta hai. Redistribution IS-IS aur OSPF, BGP ya static ke beech mein, safely, route tag aur policy ke saath. Course ke end mein aap ek chhota IS-IS design bana sakte hain, har best path predict kar sakte hain, aur whiteboard par har decision defend kar sakte hain.

Network Instructor

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


IS-IS kya hai aur iska real world use kya hai?

IS-IS ek link state routing protocol hai. Yeh mostly bade service providers aur internet exchange points par chalta hai, aur MPLS aur Segment Routing ke underlay ka kaam karta hai. Agar aap ISP, telecom ya hyperscale data center mein kaam karna chahte hain, to IS-IS aapke liye zaroori hai.

Kya IS-IS aur OSPF mein farak hai?

Haan, kaafi. Dono link state hain aur dono Dijkstra chalate hain. Lekin IS-IS Layer 2 par direct chalta hai, TLV format use karta hai, aur area boundary link par rakhta hai (router par nahi). Isi wajah se IS-IS bade networks mein OSPF se behtar scale karta hai.

Kya iske pehle koi course zaroori hai?

Nahi, prerequisite koi nahi. CCNA level ki basic routing samajh helpful hai. Agar wo bhi nahi hai, to Routing Fundamentals ya Be Job Ready in Computer Networking saath saath le lijiye.

Yeh course sirf Hindi mein hai?

Haan, yeh page Hindi only version hai. English chahiye to alag page hai. Aur dono ek saath chahiye to Package le lijiye, jismein Hindi aur English dono ek hi price mein aati hain.

Course ki language Hindi hai ya Hinglish?

Explanation Hinglish mein hai, matlab Hindi sentence structure ke saath English technical terms. TLV, LSP, NSAP, adjacency, level jaisi cheezein English mein hi rahengi, kyunki industry mein wahi standard hai. Baaki poori baat Hindi mein hai.

Kya EVE-NG paid tool hai?

Nahi. EVE-NG ki community edition free hai. Aapko sirf router images chahiye (Cisco IOL ya CSR), aur guidance course mein hai ki kaise setup karein.

Kya laptop kaafi hai IS-IS lab ke liye?

Only Wireshark itself, which is free and open source, and any laptop with at least 4 GB of RAM. There is no expensive lab license, no cloud subscription, and no special hardware.Haan. 8 GB RAM wala laptop enough hai. Physical Cisco hardware ki zaroorat nahi hai.

Kya yeh CCIE preparation ke liye theek hai?

Bilkul. CCIE Enterprise Infrastructure aur CCIE Service Provider dono mein IS-IS deep topic hai. Yahaan ki depth exam ke liye kaafi hai.

Certificate milega kya?

Haan, BridgeWhy ka completion certificate milega jab aap course finish karoge.

Interview mein IS-IS ke sawaal aate hain?

Bahut aate hain, especially service provider aur senior network engineer roles ke liye. Iss course ke saath Interview Preparation Series lene se aapki tayyaari solid ho jaayegi.

Access kitne time ke liye milega?

Plan ke hisaab se. 3 Months Access, 1 Year Access ya Lifetime Access. Lifetime sabse popular hai kyunki networking topics baar baar revise karne padte hain.

Mobile par dekh sakte hain?

Haan, BridgeWhy platform mobile, tablet aur desktop teenon par chalta hai. Theory mobile par, lab laptop par, yeh common pattern hai.

IS-IS ke baad kya seekhein?

Service provider direction ke liye BGP from Scratch aur phir MPLS from Scratch. Enterprise ke liye SD-WAN from Scratch aur data center ke liye VXLAN with BGP-EVPN.

Instructor kaun hai?

Vishnu Dutt. 19+ saal Cisco mein kaam kiya, 15000+ learners ko padhaya, 100+ countries mein. About Us page par unke baare mein aur padh sakte hain.
