What an incredible explanation! Despite watching numerous videos, I struggled to grasp the concept until I came across yours. Your excellent explanation has finally helped me understand it. Thank you!

[@LearnCantrill]

Glad it helped!

[@Machin396]

Excellent video, I learned the high level view of BGP.

[@LearnCantrill]

Glad it was helpful!

[@funmemes5915]

Excellent explanation. Cheers!!!

Prepend would be used only for traffic into brisbane AS but you need to also route manipulate traffic out to use same route in the ibgp using localpref or metric etc.
BGP is very manual system, we need to adjust both inbound and outbound nexthop to route manipulate system to ensure both way traffic is using same ASPATHS.

Thanks for this video great

[@rockinron5113]

Great thanks.

[@ilays4681]

BRO THANK YOU SO MUCH

[@boyboyfat]

are the AS path order in all 3 blue routes correct? I thought for Brisbane (i) to reach Alice Spring (202) Via Adelaide (201), the AS Path should be 202,201,i

[@subee128]

Thanks

[@vinodsr007]

This is Gold!! Thanks Adrian

[@LearnCantrill]

glad you like it :)

I thought what this video would be more agile and graphic like others, maybe networking is not easy to explain

[@BULLSHXTYT]

I think using A B C is much better than city name.

[@LearnCantrill]

Why? What difference does it make ?

[@lastraven7205]

bgp seems pretty janky compared to OSPF

[@LearnCantrill]

Why do you think that?
Most people seem to like BGP .. the core of the internet runs on it too, so adoption wise it's pretty set.

[@gwynbleidd07]

both are great and used but for different scales, between Autonomus systems is eBGP, inside of the Autonomus system mostly under iBGP is ISIS or OSPF.

[@ChannelDefault]

@LearnCantrill Perhaps because OSPF considers the bandwidth of links in its calculation of the path metric and will thus automatically select the 1Gbps path. In your example for BGP, this has to be configured manually, which makes OSPF look more intelligent.
