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

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
Great video. Well explained and I appreciate the drawn out example.
Thanks for the comment! Glad you enjoyed the video.
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?
Explained like Explaining to a 5 year old ... Amazing work !!!
you had a terrible childhood dude
Then I feel like a three year old
Is my impression or how writes backward forward?
They either use mirrors or flip it via editing I guess.
@@zsdanix how exactly ?

Hey there fellow Deakin SIT202 student sorting by new haha
7:00 Isn't it 3 for both paths? AS2->AS1->AS3 and AS4->AS1-AS3. So the difference is in ony one AS.
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.
awesome explanation !!! please make a detailed video of bgp and multicast.
Others: "You should study CCNA, CCNP, and CCIE bro"
Me: *takes CCNA, learn BGP, and took AWS
so every AS is associated with one ISP?
thank you i m from morocco north africa thanking you a lot
How is this presentation made? some sort of mirror or is it a glass

Who is watching this because FB is down? 😅🤣
I started my career in networking now I'm into cybersecurity 😊
Is he writing backwards?!?!
Great clear explanation of BGP
How this transparent writing is done?
this is how we produce these: ua-cam.com/video/U7E_L4wCPTc/v-deo.html
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
Great video, thanks!
thanks for the comment!! Glad you liked it!

Excellent explanation! Thanks!
Now i can apply for a job at Facebook, thank you
Awesome, very well explained. thank you
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
Jason : Can you do a white board for BGP RHI?
Wish this was longer
Jason Rahm : Can you make a light board for BGP RHI?
I'll add it to the queue!
That's awesome, but I was looking for the algorithm though.
Great Overview. Thank you.
is it hard to write backwards?
here after the fb/whatsapp/insta outrage
is as2 directly connected to as3?
as2 is the iApp predecessor to the as3 declarative rest interface.
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.
Perfectly informative.
Optus brought me here. But not because they’re my ISP.
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? :)
Well... this was awesome. Suscribed.
Who has come here after learning what brought Facebook down.
You legend! Really helped me out!
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.
Hi Zuckerberg
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
Nice explanation!!!
Good intro.
I am here to understand why facebook wen down today
How he can write backwards just like that!? AH! Horisontal mirror video.

Bring back the dislike count.
not a very good explanation! he digresses too much one thing to another
great tutorial but speaks too fast...
It not like this to explanation and make other to understand this méthode this gay have complicated this
