Spine and Leaf network architecture explained | ccna 200-301

[@aliciamarques3743]

Best explanation of spine-leaf I've seen. I was having trouble understanding but now it makes sense...thank you!

[@liquidninja6654]

Omg you actually made it so easy to understand! Most network engineers skip the obvious and assume everyone is an expert. Bravo.

[@networkingwithh4716]

Great :)

[@juliotableta-android2061]

Quick and concise explanation. Thank you!

[@frzen]

Thank you for including the wan... no other video shows where the wan connection is in spine-leaf. The bit I don't understand is when it's bigger than a small datacentre... if you have 40 spines your rack switches would need 40 ports just to reach the spines. But 4 spines makes perfect sense just connect your top of rack switches to the 4 spines each

thks!!

[@mickaelf-b2937]

Hi, EoR stands for End of Row not End of Rack.

[@SheikAbdulKaleem]

How will you build campus network using Spine and leaf as there will be too many cables, If there are 10 buildings it can be nightmare. How does this work in such a scenario ? Kindly guide me if you have any video on that.

[@anantgaonkar941]

Made it simpler!

[@evolagenda]

Can you talk more about the concept of top or rack switch?

[@networkingwithh4716]

noted..

[@laserspud]

Hi I would like to ask. Can this architecture be used for a network campus? and if so, where would devices such as laptop be placed? would it be attached to one of the switches? thk in advance :)

[@networkingwithh4716]

It is a nice question... Spine and leaf are mostly used by data center networks. laptops are connected to Access network through Wi-Fi or lan Switch

[@laserspud]

@@networkingwithh4716 oh i see, thk for answering my qns 😄 im trying to make a campus network but i’ll stick with a 2 tier topology. That video u made on 2 tier topology was very good btw, understood it very easily 😁

[@rkbwebmaster]

how full mesh ?

[@kayazar5387]

Hi sir, is two-tier architecture and spine-leaf architecture same?

[@networkingwithh4716]

They are not same. One of the major difference i see is you can use layer 3 routing between spine and leaf in spine and leaf architecture. Any traffic between two nodes is just one hop away and it uses full available bandwidth. where as collapsed core or 2-tier hierarchical model is limited to spanning tree and vPC. which might not allow us to use full available bandwidth.

[@kayazar5387]

@@networkingwithh4716 Thank you sir, what about the cost which one is cheap?

[@networkingwithh4716]

@@kayazar5387 cost depends on what devices you choose to use..modern networks specially data centers prefer leaf and spine.

[@Secretsauceeee]

Hi sir, noob question, what is the difference between a collapse core and a spine-leaf?

[@indrajittalukdar4904]

Hi, can you explain a bit about the non -blocking fabric. If there is no interconnection between leafs and spines themselves will create a non-blocking switch ? how ?

[@networkingwithh4716]

That is a good question... Non-blocking means that each port is capable of sending and receiving traffic at the maximum speed to and from any other port
