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.
If they are both transit providers, then they are broken. If they are peers, the second ISP is probably preferring the route it hears through your transit provider because there are fewer AS hops. -- TTFN, patrick
