MicroNugget: BGP Configuration Explained | CBT Nuggets

We love oranges as oranges mean pure refreshment

nice video ! i have a tough question : can you change routes to a network on a router depending on which source loopback you use without using PBR ?
its in one of the labs that i found . any help would be appreciated , thanks !

Finally a simple video to understand how BGP works, thank you so much

what if the local preference attribute was not set to default (100)

what i he using to configure the systems??

Hi i have a problem in my epgp with multi isp in mikrotik router. In a day 5 to 6 packets getting dropped from an outside network which means blackout our network users between the duration. What was the issue can you help I can't figure it out.

This is the best video I've seen to explain how this works. I am a visual learner, so this works for me.

Lots of light bulbs went off with this video. Much appreciated

Makes it sound so simple but this is only the beggining. What happens when the path has equal number? When does Local Pref and Remote Pref come into effect? Then theres Tags

I Love Keiths teaching style he is the best

Whay about weight, Local Pref, then shortest AS_PATH

thank you for the video, very helpful!

Isn’t the shortest path an ospf thing for the first decision?

Bgp first looks for the path with the highest weight, and the shortest path is the 4th decision. Just a clarification

Hahaha a /12, Sure!!! LOL

Solid explanation. I dig it...

Amazing!

This is so well explained and explained by Keith. Well explained for me and impending CCNA exam. Very relevant in age of FB down earlier this week.

11 yrs old video, but still it's the best to video to all the network engineers who just lost their basics and also the best video to all the novice network engineers.

Great Job Keith.

Brilliant

Thanks for the easy brief introduction to BGP, still one of the best vids out there.

What of the route was the same size on both of the paths? How does it choose which one is the better one?

Hey guys from CBT Nuggets, How did you program that explanation example you put at the end? I'm currently studying BGP and I want to include an explanation video just like that one you guys did in my presentation. Thank you

BEST video ever

8 years old... and still the best video I managed to find on this! Great job, thanks!

These guys are the best teachers.

Hello Keith, thank you very much for clear explanation, Could you please consult Mr.Jeremy how to teach or train him how to explain It, I listened to all his nuggets audios for almost 7 months, I couldn't understand him and DOES NOT KNOW the method to explain these It subjects clearly, he always around the bush/confused not coming up with a clear explanation, he is just goofing, I am an instructor for almost 15 years, please let him know, he needs to get his act together.

Simply love this channel✌🏻
As junior networker, it's my Bible 🏅

Which software was that ?

Very confused, Just explain the BGP functions, don't be around the bush.

What is the program that you are using to type your commands?

Thank you for the video. Is it only the BGP routers in each AS that participate in BGP then? And how many BGP routers do you need for an autonomous system (AS) based on the number of routers in the network?

It looks like it chose the shortest as path route BECAUSE of LOCAL_PREF not because of the shortest AS path.

Thank you very much Keith, great BGP intro video it makes a lot more clearer now... :))

This is not entirely true. It does not necessarily look at just the shortest path. The BGP routers look at whether the path came from a customer, a peer, or a provider. BGP routers will avoid using providers as it costs them money to use, and will not advertise routes that came from a provider to other providers or peers. For example, a peer can take advantage of such a path and use the route though the advertiser because it will not get charged for it, causes the advertiser to get feed.

As in show output local preference was 100, and your saying it's due to as path....

PLEASE TEACH US MORE LIKE THESE, ONCE I GET HIGH SALARY I WILL ENROLL TO YOU CBT NUGGETS I PROMISE THAT!

nice excellent video

wrg,idts

Awesome presentation..Many thanks!

Keith's vids are always inspiring. I wish he has more detials for BGP in his personal channel.

Hi Keith, thanks you doing this video. I have a silly question. Does the BGP not take into account the time taken between two ASNs? What if the time for the longer path is actually faster because it has Google fiber or some other fast connectivity between them?

Thanks!

Nice video Keith! Inside each AS, there could be half a dozen hops and increase latency. Does BGP have a mechanism to calculate that?

Thanks it was very helpful!

Might make the head of one who's not familiar with the mechanics of IP, but for someone who knows how IP works on a LAN, very helpful. What tool were you using? Did you have a bunch of routers that you telnetted into, or is that like a router emulator or something?

Excellent video! I'm studying for some IT certifications and have learned a lot about TCP/IP on a LAN, but I've been curious about how it works on the Internet. Thanks for sharing.

Thanks for your post Pete! Keith

MED is (normally) only a factor when there are multiple links from one AS to another AS, and your question only applies if the routers within one AS are running vastly different software versions so as to pick different favorites. The "incomplete" is merely an origin code, not an incomplete ASN.
