You have to compile on a recent Linux that has multiple routing table
support in the netlink libraries.  Fedora 8 and later works without
having to manually hack include files, other recent distributions probably
work as well.

Please note that if you want these routers to talk to each other, you
also need a lot of clever ip rules and you will also need some patches
to the Linux kernel.  My company has these patches available...if you
are interested, let me know and I'll send you a link.

If you are just using the xorp to talk to external systems, you
probably won't need any additional patches.

Thanks,
Ben
