BGP Overview

Interviewer: "Would you explain what's BGP?" Me: "It's the duct tape of the internet"

[@kirisutegomen12]

Lol I can't really explain it

and given the Facebook issue today, am I wrong? :)

[@pezictusfish]

@@JasonRahm Haha!

[@Ioganstone]

If you want 1 slightly higher level of resolution, "It's looking at antonymous system hops not router hops." 7:20

[@daniyalahmed7102]

guy is also wearing a backward texted Shirt, they really thought everything through. amazing

[@rahul_bali]

that became a riddle for me.

[@sten32144]

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

[@Kmarad_]

ooc did you think the dude was writing backward ?

[@AndyCutright]

@@Kmarad_ Yeah i think the guy is writing backwards

[@kellymoses8566]

α trick would be to get α reversed shirt when you do this.

[@specialagentjerrylewiss]

Just an security admin of Facebook here learning how to reset this..

[@quicktutorials7662]

Lol

[@Emmanuel-so9eo]

😂😂😂

[@kellymoses8566]

Oopsie

[@shonkylogic]

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.

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

[@caquintella]

Is my impression or how writes backward forward?

[@zsdanix]

They either use mirrors or flip it via editing I guess.

Great video. Well explained and I appreciate the drawn out example.

[@devcentral]

Thanks for the comment! Glad you enjoyed the video.

[@mavicomania]

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?

[@JasonRahm]

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.

[@mavicomania]

@@JasonRahm wow, that was fast. Keep up the great work!

[@septiq3105]

you had a terrible childhood dude

[@fabiolichtler751]

Then I feel like a three year old

[@omegaamigo]

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? ;-)

[@devcentral]

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

[@omegaamigo]

F5 DevCentral Thanks :-)

[@Encoder001101]

@@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.

[@ast3citos]

@@devcentral So you have the logo in you tee embroidered backwards?? Great video man, you are the best!

What kind of tool or device you are using for teaching the stuff.

[@devcentral]

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.

How this transparent writing is done?

[@migueljo3980]

Border gateway protocol is an advanced distance vector routing protocol.

[@JasonRahm]

Miguel Jo we may be into semantics, but BGP is more accurately a path vector routing protocol.

[@redhook34]

It's a path vector protocil

[@SuperMaDBrothers]

Is he writing backwards?!?!

[@AllenAndersonTaylor]

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...

[@JasonRahm]

Allen Taylor it is a path vector protocol because you get the AS path as a decision rather than the actual hop distance.

[@ayouberrazki5602]

Nope it has to be configured on other communicating router , HRP is a hybrid protocol

[@purplemonkeydishwasher5269]

The link to the article is broken

[@devcentral]

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 it hard to write backwards?

[@jay-rathod-01]

is as2 directly connected to as3?

[@JasonRahm]

as2 is the iApp predecessor to the as3 declarative rest interface.

[@arnavlogs1270]

Excellent explanation! Thanks!

[@zoltron30]

So private IP addresses are definitely reputable but I guess ISP's filter those addresses on there edge routers

[@devcentral]

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.

[@zapino2535]

125.4.5.0/24 aggregated in 125.4.6.0/20 ?

[@JasonRahm]

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.
