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!

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.

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

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