This is a limitation of the BSD IP stack. In "TCP/IP Illustrated Vol 1",
W. Richard Stevens states (on p. 114) that multiple default routes may be
supported (he mentions Solaris 2.2 as an OS with this capbility)
Is there any taker for this addition to FreeBSD ?

PS : this an excerpt from man 4 routing on a Solarie 2.5 machine :
<begin quote>
A wildcard routing entry is specified with a zero destina-
tion address value. Wildcard routes are used only when the
^^^^^^ this is **plural**
system fails to find a route to the destination host and
network. The combination of wildcard routes and routing
redirects can provide an economical mechanism for routing
traffic.
