In the above scenario, I am using AS30 and I need to access AS1. The
outbound traffic can be force using the localpref to prefer which
path I can use for the outbound however, my dilemma is the inbound
traffic. Since sample 1 and 2 has lesser path from AS1 going to AS30,
this might be the best in returned path while sample 3 is the least
priority due to longer path. Is there a way can I manipulate the inbound and
outbound via sample 3 without contacting AS1?
The short answer is as-path prepending of your announced routes to as200
and as300.
