Current best version for router use

I have been using FreeBSD 8.0 and as well 7.2 but from a routing perspective
i would say you could go ahead with 8.0 for the reason being 7.2 still does
not support ECMP but 8.0 supports ECMP which is quite important but having
said that load balancing and fast protection has got issues in 8.0 too but
from a longer run 8.0 would be better choice as Qing and other few people
are putting lot of fixes to flowtable and general routing infrastructure .


Hope this helps

Thanks,
Cheers,
