don't think this will help as a locally-originated route is preferred
over almost anything due to the higher weight (32768, if I recall
correctly), so the eBGP path will not be installed (and would win over
the static due to admin distance). you need to set the weight on the
eBGP path to be the same (or higher) value or reduce it to zero (to
match the eBGP path) when redistributing the static (not 100% sure if
the latter works, I think it does)..
