Zebra

zebra is a recommended replacement for routed, available from the ports tree.

From /usr/ports/net/zebra/pkg-descr:

GNU Zebra is a free software (distributed under GNU Generic Public License) which manages
TCP/IP based routing protocols.

It supports BGP-4 protocol as described in RFC1771 (A Border Gateway Protocol 4) and 
RIPv1, RIPv2 and OSPFv2.

Zebra uses multithread technology under multithread supported UNIX kernels.  However it
can be run under not-multithread supported UNIX kernels.

Zebra is intended to be used as a Route Server and a Route Reflector. Zebra is not a
toolkit, it provides full routing power under a new architecture.

See the entry on routed for caveats regarding whether you do or don't need a routing daemon in the first place.
