You could use load sbgp/mrtd script to load route dumps. There is also bgpsimple
This also brings up another question, anyone know of v6 rib tool on unix to load v6 route dumps.

Roll quagga / BGPd on *nix and bring up sessions with whatever you like.

For full tables, you can either hack up a few lines of perl to output a bunch of 'network a.b.c.d' lines from any of the available text looking glasses into the bgpd conf, or just bring up ebgp-multihop session with one of your borders or one of your friends. Prefix lists, communities, etc are all supported.
