This is how you can do it with Quagga:
http://wiki.nil.com/Use_Quagga_to_generate_BGP_routes
You could write a Perl (or whatever your favorite scripting language is) =
script to get Quagga/IOS configuration from live BGP data, but it would =
be non-trivial and the resulting configuration would be enormous. I know =
there was a similar discussion months ago on the NANOG mailing list; =
browse the archives.
