Update: I am prepending my AS 3 times to the un-preferred ISP. Both ISP's are my peers. The un-preferred ISP claims the see my advertisement yet they do not add it to their routing table (suggests filtering??). They claim all the filtering they are doing is based on the networks I told them over the phone that I was using with that AS. Philip --- Jon Lewis <jlewis@lewis.org> wrote:

I am using AS prepending to favor one ISP over another, in a BGP multihomed/multiISP scenario. Why does the ISP receiving the prepends fail to add my network into their routing table? Is this a "feature" of BGP, or have I gone too far with 3 prepend statements.
Who's ASN are you prepending on your advertised routes?
