On a related note : Do ISPs ever tweak around with Local Prefs and weights so as to select BGP paths with greater AS PATH length?
Would it ever make sense for a provider to chose a longer AS PATH length BGP route against a shorter AS PATH length route?
Yes many do -> Prefer your customer routes via customer interfaces, over transit and peering interfaces. Higher LP over cust interfaces = more bits = more revenue. There is nothing wrong with this IMO, considering many of them who do this, also provide a community for customers to override this behaviour. -J -- James Jun TowardEX Technologies, Inc.
