I've read some BGP Limitations in student guide 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."
Is it 100% correct? As i assume that we can control this behavior by various policies, at least when we are peering with provider (where provider is in touch with us).
Any other limitations in theory or practice?
