Golden Rule of BGP

BGP does not enable one AS to send traffic to a neighbor AS intending that the traffic take a different route from that taken by traffic originating in the neighbor AS. RFC 1711

While preparing for my CCIE, I came across with the above statement showed as Golden Rule of BGP but believe me I didn’t get what it means while reading for the first time, in fact after reading more than ten times I got a little bit, then after some help and consultancy I got the whole idea, let me explain what it means:

“This simply means that don’t tell a person how to work” means that we are not allowed suggesting other AS traffic to follow which path or another servide provider tell us what to do.

Cheers :)
