Listen "The Effectiveness of AS Path Prepending (2)"
Episode Synopsis
Last week I began discussing why AS Path Prepend doesn’t always affect traffic the way we think it will. Two other observations from the research paper I’m working off of were:
Adding two prepends will move more traffic than adding a single prepend
It’s not possible to move traffic incrementally by prepending; when it works, prepending will end up moving most of the traffic from one inbound path to another
A slightly more complex network will help explain these two observations.
