>Description:
When you use the kernel option ROUTETABLES to enable multiple FIBs, there is not clean way to manage the static routes (including default gateway) for those FIBs

this is an /etc/rc.d script to do that, based on /etc/rc.d/routing and static_routes in /etc/rc.conf

>How-To-Repeat:

>Fix:
in /etc/rc.conf or the like, configure like this:

fib_1_routes="default sitea"
fib_1_default="default 192.168.0.1"
fib_1_sitea="-net 192.168.1.0/24 192.168.0.2"

fib_2_routes="gate"
fib_2_gate="default 10.0.0.254"
