Please read the history of this thread, as there has been extensive 
discussion on this subject. FreeBSD doesn't need to have a RIB, that's a 
job for routing control plane software such as XORP and Quagga/Zebra.

There are strong arguments against using the kernel forwarding tables as 
an exchange medium, the strongest one being "that's not what it's for".

Thanks.
