I don't remember how FreeBSD 10.1 did it, but in FreeBSD 10.2 the number 
of routing tables (e.g. net.fibs=2) is a boottime loader tunable and can 
be changed in /boot/loader.conf without rebuilding the kernel. Moving 
from 10.1 to 10.2 is a painless way to gain this feature if it isn't 
available in 10.1 already.
