My own experience was that I tried to use the 2000::/3 route initially and
that was fine with static routes in my lab, but once dynamic routing
protocols were introduced, ::/0 was the only thing recognized as "default"
to propagate or not with default-route statements in BGP and OSPF.
That may vary from platform to platform, however the ones I played with all
exhibited this behaviour.
