Yes, works with ci$co, doesn't with FreeBSD ;)

You cannot add more than one next hop for any given prefix.
Well, you can achieve almost the same result, but only with
the help of a packet filter which can bypass the routing table
lookup and forward to the next hop of preference. But that's
hardly the same with ECMP which many vendors support...

Yet, that's about to change. There is ECMP support in 8.0:)
