I hacked Zebra to do this a while ago.  All you have to do is bring up
Zebra with a router that has full routes, save them to disk and off you go.
The advantage here is that you get realistic NLRI and path attributes which
you don't get with an IXIA or SmartBits.  And Zebra has good BGP feature
support so you can use route-maps on the prefixes you load, for example.

It is not a particularly pretty hack, but it works.  You can find the
patch at .
