Tuning Inbound Load Balancing! Ep.9: Real World BGP

[@miguelk8768]

This is one of the best BGP series out there, appreciate the real life configuration examples! :) would love to see more content like this. Thanks Jeremy!

[@guzmanfreigedo1181]

This BGP Series is amazing. Thanks Jeremy!

[@jkbbv]

Agree!

[@geogmz8277]

Love this guy.. He promised it.. He delivered. 🔥✌🏻

[@hassinba]

Still the king of network training

[@hari7Ajay]

An amazing series ... and keep up your enthusiasm ... that's infectious!!

[@ejm110]

Network Lessons is a very good resource for learning. Concise and simple explanations!

[@vikaspotadar]

Very much informative!!!

[@jightning]

It's surprising how few network engineers are comfortable with this topic

[@Michael-er8dh]

So awesome to see bgp action in real world, Thanks Jeremy!

[@christianbenedectsupnet7170]

Thank you for this series Jeremy. Please keep doing these types of content. This really helps us aspiring network engineers.. Kudos to you!!

[@peterhunte]

Thank you for a great video and the information taught

[@klajdigjoka2157]

great explanation on prepending but nowdays it has little to no effects on inbound traffic because all big internet providers apply communities on routes learned and set higher local preference to those prefixes learned directly from their routers wether you prepend your subnet 1 time or 100 times

[@troxofthetrade]

Awesome video! Only thing I wasn't sure on was the exact reasoning for needing the permit 20 in the IM-AS-PREPEND route map.. can anyone elaborate on this for me?

[@williebrown4266]

Excellent video, Jeremy.

[@thebsfamily2236]

Amazing video!!

[@georgemavimbela]

Very helpful...

[@manishkad9284]

Another great video.. however a question arises.. As I remember at one of sites for our client there were couple of circuits and one of them totally being unused , so we used AS path prepending to manipulate traffic going to outside world, so do we use AS PATH PREPENDING for both manipulation of inbound as well as outbound traffic, I watched in old BGP series of your where u told we can use MED to manipulate incoming traffic from isp.

[@stephen8253]

For outbound you can use local preference , for inbound you use as path prepending. I think the MED attribute is not passed when it is advertised to eBGP neighbor.

[@nialldonaghy5940]

@@stephen8253 MED is absolutely passed, often MED is set to IGP metric. When another AS has two paths to yours otherwise equal, MED can be the tie-break. If MED is IGP, then the other AS uses the path which then has the shortest IGP path inside your network, rather than nearest exit to yours.

Was a little bummed out to find out Jeremy doesn't know Rene Molenaar. Refering to him as "some guy" lol.

"I hope this has been informative for... Iron Mountain, and lower the costs" 🤪

[@Vishalbhosekar659]

You are awesome

[@SynACK244]

I used to think if BGP as a scary topic and out of this world.

[@juanalbertocorniel]

can your ISP drop your prepending?

[@Viatto]

If they choose to, yes. However, I've never encountered on that does. It doesn't benefit them to do so (less paths means more traffic through THEIR system).

[@juanalbertocorniel]

@@Viatto in my case for some reason that I don't know my ISP drops my prependings and I'm balancing the incoming traffic sending a different /24 route to each ISP and a summary route to all. Using NAT I move my inside networks from one ISP to another
