"Unlocking Network Scalability: The Power of Route Reflectors"

[@chanakasandaruwan3065]

Your videos are very practical and easy to understand. Thank you for your effort

[@arjuverma1882]

Dear Sir, Thanks to provide such a wonderful classes on BGP, i checked with many of videos with other person but in your videos all concepts get clear with step by step, thanks to make it free on KZbin it will helps to learn.

[@nagarajthalluri7436]

you are the gem of networking world Sikandar Ji

[@dnfwme]

Thank you so much for all of your hard work.

[@vinukumar2763]

All the lectures are really nice and helpful.

[@harshavardhana5907]

your teaching is amazing. Thank you

[@ahmedh3176]

Great explanation! Thank you so much for this!

[@nabarajpoudel4272]

I think like i have missed the whole piont. Since we need to config IGP for reachability for IBGP , whats the point of using IBGP. Its just the extra line of configuration .

[@SIKANDARshaik]

You’re right that IGP is used to ensure reachability between BGP peers, but the key point of using iBGP lies in its ability to handle the exchange of routing information within an autonomous system (AS). While IGP ensures reachability, iBGP allows you to efficiently share external routing information throughout your AS, ensuring that all routers have a consistent view of external routes. Using iBGP, particularly with route reflectors as discussed in the video, helps in scaling your network by reducing the number of required connections compared to full mesh iBGP. It’s not just an extra configuration but a critical step in managing larger and more complex networks. Hope this clears it up!

[@lokeshmudhiraj2482]

sir here r2 RRsever you mentioned only networks 20.0.0.0and 2.0.0.0 and 1.0.0.0 then why didn't you mention 10.0.0.0 network.

[@nagarajusadula4507]

sir where is the one more lap video using 2 server did you uploaded or not searched lot haven't seen could please share me asap

[@cmendi22]

Excellent explanation of each topic ..

[@oomoreno23]

Very good explanation Sikandar Shaikh.... Thank you..

[@MakkahMadinaShots]

can you please share the Documents on BGP.

[@vkankata79]

Thank you , great video . Pls keep posting .

[@madaraekouta8058]

This part is not available on your udemy Encor course . you need to upload it... Your explanation are crystall clear..

[@jangragaurav1234]

When configuring BGP on loopback, don't we use IGP for reachability?

[@nabarajpoudel4272]

thats what i was wondering , previously we are told to use IGP for reachability but why not here.

[@tarifsit01]

Great

[@MakkahMadinaShots]

Jazakallahu khair.

[@rohscx]

Thanks

[@Aquahutch702]

Good overview. I do wish there were more tutorial videos where the route reflector is not placed in the data path (out of band).

[@lalosalamanca7131]

I agree..

[@aimenali2261]

Can you please share the route reflector configuration for two server's with redundancy

[@kranthi903]

its also use for small networks bocz in large network every client router is must connected with server to enable communication between 2 or more clients as per this video.but assume i had 50 routers connected in different places out of this 50 i make 1 router as a server remaining 49 as clients.that means remaining 49 directly connected to server its expensive.any suggestions pls

[@SirAkshayJoshi]

Sikandar bhai, why suddenly change in topology? From 4 router to 3 router?

[@ankhancam6761]

Thank you sir.

[@MrWinfil]

thank you my bother.

[@tanujsinghal9587]

How can I get this PDF ?? Your videos are really great. In comparison to INE which charge 850 USD for one year. Your videos are free and helpful for students with low resources.

[@lkdipeolu]

Short and precise. I need the documentation. Thanks.

[@punkeyengineer]

where do download your documentation from @sikandar shaik

[@amirrezaazmoode8850]

If the RR scenario is not chosen, why there is a need to make a full mesh neighborship? Doesn't it suffice that every iBGP router makes a neighborship to iBGP routers who are connected to eBGP routers?

[@rogeriosouza9288]

I think you are misunderstanding things. Let me try to clarify, you need full mesh inside the same AS (iBGP). That's because of the split horizon mechanism BGP implements, as he explained before. But that's not good for several reasons, so a RR can be used to decrease the number of neighborship/tcp establishments. So, eBGP does not come into picture in this case. For eBGP, AS-PATH is used as a loop prevention mechanism.

[@m.n.shaqib7599]

But sir, what are the commands for neighbor server to server ?

[@classiscartoon]

AOA for example we have one more router next to c ...then what server make session with this client ?

[@baluforu9305]

You have well explained this concept. But a question raising for me is Q: In R1, we are receiving the 30 n/w through RR with nexthop 2.2.2.2(it is directly connected on R3) in such case how my R1 node will reach 30 network ? how we can change next hop address ? i think we can't modify RR update. Thanks i advance

[@pandil9802]

Very nice explanation.Keep it up...

[@aptamse1]

Thank you for uploading ..

[@shivamchaurasiya1542]

nice explanation

[@SmackDown-yx7zw]

If we want to use loopback , IGP (OSPF,RIP,EIGRP) use is mandatory ?

[@abhiram3240]

Same doubt

[@warriorrace1793]

yes

[@rogeriosouza9288]

Actually you can use static routes.

[@catthypace]

you need to use any of the IGP protocols such as Static, OSPF, RIP, EIGRP to ensure the reachability.

[@khareprateek19]

sir i am huze fan of your but your document link is not working for me please help

[@narinderpal61]

Many thanks - How can I obtain a PDF?

[@prashanthkalleda]

how can we mention or configure which is primary server or secondary server ?

[@ALHAQQACADEMY]

there is no primary or secondarY

[@prashanthkalleda]

@@ALHAQQACADEMY one we configured route reflecter for servers, servers will be in active/active or active standby

[@catthypace]

In Pri R2 you will mention that Sec R4 is Client. In Sec R4 you will not mention Pri R2 as Client, simply peer it. In R4 you will mention other routers R1 & R3 as Client.

[@ajithm1138]

can you please explain the route reflector with peer groups ..

[@dharaniraj5042]

why remote-as is used in most of the bgp config i am new to it can explain it please

[@nilashishchakraborty3983]

remote-as is used to identify whether to use IBGP or EBGP. If the remote-as is same, IBGP will be used, else, EBGP. You can watch all the videos from the starting to understand the concept.

[@ashwinichikane2612]

can we get pdf for this ?

[@lalitverma8352]

Hi Thanks for such videos can i get the documents .

[@krishnap6014]

Do we need to advertise IGP protocol in case if we use 2 RRservers .. or BGP is enough please do help

[@kishorekumar8436]

+ krishna, By Default Split Horizon is running between IBGP router,so you need to advertise the IBGP route as RR client.

[@mohiuddinshahbaaz]

You need IGP protocol to reach from one RRServer to another, also if you are making neighbor ship with loop-back interface.

[@gaurav6738]

is it necessary to directly connect every client with RR Server?

[@SIKANDARshaik]

yes it can be conected or not ( as long as reachable that wil works)

[@abhiram3240]

@@SIKANDARshaik for reachability should we use igp(OSPF/RIP/EIGRP)? For example if there is a router which is not directly connected to server.

[@SunilSingh-nl3zl]

@@abhiram3240 Yes routers must be pingable even they are not directly connected.
