We, JPNAP, tried both network.
At first, we built separate IPv6 only IXP named JPNAP6 on 2002.
Next, we built dual-stack on exist JPNAP on 2005.
So JPNAP has already tried both network configuration.

AFAIK, I cannot see major problem for both case.
Only one thing I can see is it's difficult to get
IPv6 traffic from dual-stacked network using sFlow
because traffic volume of IPv4/v6 is totally different.
Sampling rate for IPv4 is not fit for IPv6.

As you like.
We choose bi-lateral.
