I'm ver new to the freebsd so I don't know the internals but from my
point of view ECMP in freebsd is handled with the module RADIX_MPATH.
RADIX_MPATH is included into the normal freebsd kernel source but 
not active in all builds. 

Most distribution which are specialized for routing or firewalling 
have it enabled ( pfsense, bsdrp and so on). On freebsd you can see 
іf it is enabled via sysctl for example:

[root at gw01]~# sysctl -a | grep -i radi
options RADIX_MPATH
[root at gw01]~# 


It could be that you can find some examples in the quagga source code,
cause I have found some people using it with quagga.

It would be nice If we can use it. If you got an path to enable it.
