BGP Overview
Вставка
- Опубліковано 19 тра 2024
- Jason Rahm reaches into his "router guy" past to give a brief overview on the border gateway routing protocol (bgp) that keeps the internet duct taped together.
F5 specific BGP resources linked here on the DevCentral article: community.f5.com/articles/lig...
Corrections:
05:45 I mis-spoke here, there is no direct path from AS2 - AS3, that path would actually have to be AS2 - AS1 - AS3 - Наука та технологія
Interviewer: "Would you explain what's BGP?"
Me: "It's the duct tape of the internet"
Lol I can't really explain it
instablaster
and given the Facebook issue today, am I wrong? :)
@@JasonRahm Haha!
If you want 1 slightly higher level of resolution, "It's looking at antonymous system hops not router hops." 7:20
guy is also wearing a backward texted Shirt, they really thought everything through. amazing
that became a riddle for me.
DUDEEE.... i was thinking just the same :D - what the hell? but his buttons are mirrored, so its clearly a shirt with mirrored text in 1st place
ooc did you think the dude was writing backward ?
@@Kmarad_ Yeah i think the guy is writing backwards
α trick would be to get α reversed shirt when you do this.
ATT network engineers might need to reference this video after recent events
What about today fb ig outage?
I see from the link further down this video was flipped in post-production, so he's not really writing backwards. But what is really impressive is that the DevCentral logo on his shirt appears the correct way around, so he must be wearing a shirt with a back to front logo... nice touch.
oh my
I'm here because of Facebook's oppsie
Just an security admin of Facebook here learning how to reset this..
Lol
😂😂😂
Oopsie
Wow, where the hell was this guy all throughout my high school days ?
Great teacher..!! - Can you do more Cisco network videos please. thanks :D
Clear and concise, THANK YOU
Great video. Well explained and I appreciate the drawn out example.
Thanks for the comment! Glad you enjoyed the video.
thank you i m from morocco north africa thanking you a lot
awesome explanation !!! please make a detailed video of bgp and multicast.
Great stuff! Thank you. Would love to hear a follow up story talking about the IGP->EGP injection.
Thanks for the comment and we'll pass on the topic request!
@@devcentral was worth a shot 😅
Awesome, very well explained. thank you
Great Overview. Thank you.
Excellent explanation! Thanks!
Explained like Explaining to a 5 year old ... Amazing work !!!
you had a terrible childhood dude
Then I feel like a three year old
Great clear explanation of BGP
Perfectly informative.
Who is watching this because FB is down? 😅🤣
You legend! Really helped me out!
Is my impression or how writes backward forward?
They either use mirrors or flip it via editing I guess.
@@zsdanix how exactly ?

@@devcentral Thanks for taking time and sharing!
He's a wizard
Excellent video, one question is nagging me ... Are you actually writing this all *backwards* on your display, or have you flipped the entire video left/right? ;-)
I can barely walk and chew gum at the same time, so writing backwards is not in my skill set! We flip the video in post-prod. For a full look behind the curtain, including build details, check out our article on DevCentral: devcentral.f5.com/articles/lightboard-lessons-behind-the-scenes
F5 DevCentral Thanks :-)
@@devcentral Great video, Jason! I too was curious about the display, and at first I thought, "oh, they must just flip the video in post-processing," but then I realized that the DevCentral logo on your shirt would be backwards and thought that couldn't be right. I turned to the comments, and watched the behind the scenes video to confirm that the logo-less shirt flipped right along with the display. Am I wrong, or is that a reverse logo on your shirt? Seems like the only reasonable explanation.
@@devcentral So you have the logo in you tee embroidered backwards?? Great video man, you are the best!
He's a wizard
Wish this was longer
Hey there fellow Deakin SIT202 student sorting by new haha
Nice explanation!!!
Jason : Can you do a white board for BGP RHI?
Is BGP considered a Hybrid protocol? I've heard path vector and Professor Messer says Distance vector. A practice test I took said it was hybrid. I'm very confused...
Allen Taylor it is a path vector protocol because you get the AS path as a decision rather than the actual hop distance.
Nope it has to be configured on other communicating router , HRP is a hybrid protocol
Is he writing backwards?!?!
Zero trust, is the best trust.
Zero, nada, zilch! Agree and thanks for the comment!
Border gateway protocol is an advanced distance vector routing protocol.
Miguel Jo we may be into semantics, but BGP is more accurately a path vector routing protocol.
It's a path vector protocil
Well... this was awesome. Suscribed.
How is this presentation made? some sort of mirror or is it a glass
devcentral.f5.com/s/articles/lightboard-lessons-behind-the-scenes
so every AS is associated with one ISP?
is it hard to write backwards?
What kind of tool or device you are using for teaching the stuff.
magic! But seriously, we are using a sheet of low-iron glass with LED strips shooting light into it from all sides with a black sheet as a backdrop and neon markers that really pop on camera. We flip the image in post-production so you see it the way I am drawing it.
Great video! But I think there's a mistake at 5:45? IMHO AS2 doesn't have a direct path to AS2 nor does AS2 split out at all ... Right?
yeah, good catch, no direct path from AS2 -> AS3 (as drawn), that has to bounce through AS1, which I do mention 20 seconds or so later. I added a correction that will pop-up at that timecode.
@@JasonRahm wow, that was fast. Keep up the great work!
@@JasonRahm i didn't see any correction, how would this work?
Now i can apply for a job at Facebook, thank you
Have you ever served on a naval carrier? That is great mirror manuscript skill!
I received (but did not accept) a naval ROTC scholarship in HS...does that count? :)
Great video, thanks!
thanks for the comment!! Glad you liked it!
Thanks!
Hi Zuckerberg
Jason Rahm : Can you make a light board for BGP RHI?
I'll add it to the queue!
here after the fb/whatsapp/insta outrage
AS5 certainly is an interesting one, isn't it?

I started my career in networking now I'm into cybersecurity 😊
The link to the article is broken
Thanks for the note! I believe the link went to the DevCentral Article of the same video. Pretty sure this is the new link: community.f5.com/t5/technical-articles/lightboard-lessons-bgp-overview/ta-p/279037
and an updated BGP article here: community.f5.com/t5/technical-articles/using-ansible-to-manage-bgp-on-big-ip/ta-p/296606
is as2 directly connected to as3?
as2 is the iApp predecessor to the as3 declarative rest interface.
How this transparent writing is done?
this is how we produce these: ua-cam.com/video/U7E_L4wCPTc/v-deo.html
So private IP addresses are definitely reputable but I guess ISP's filter those addresses on there edge routers
Yes, ISPs should definitely filter private IPs out from public route table propagation. A caveat to that might be for tunneling protocols with customer-to-customer "extranet" solutions, in which case all parties are in agreement and there are filter protections from leaking that into the wild.
That's awesome, but I was looking for the algorithm though.
Good intro.
125.4.5.0/24 aggregated in 125.4.6.0/20 ?
That CIDR block is 125.4.0.0/20, not 125.4.6.0/24. The latter wouldn't be a legal network, but would be a legal address.
Optus brought me here. But not because they’re my ISP.
Who has come here after learning what brought Facebook down.
I am here to understand why facebook wen down today
Am i too dumb or this guy is writing in reverse
Not dumb nor writing in reverse. :-) This is how we produce these: ua-cam.com/video/U7E_L4wCPTc/v-deo.html
What a mess with hard-writing , PPT, need to learn how to create nice PPT
How he can write backwards just like that!? AH! Horisontal mirror video.
thanks for the comment! Here is how we produce these: ua-cam.com/video/U7E_L4wCPTc/v-deo.html
great tutorial but speaks too fast...
Bring back the dislike count.
It not like this to explanation and make other to understand this méthode this gay have complicated this
