Re: exchanges with both native IPv4 and IPv6?

NSPIXP-2, one of the IXes in Tokyo downtown area, has been operational
in IPv4 and IPv6 for a couple of month. Many ISP operators do have
concern on the stability of the routers when dual stack software is
running, and they prefer to use separate IPv6 connections (most of
them are FastEthernet).

We have no specific problems in IPv6 -- you may want to encourage the
participants that their router won't speak RA pacekts to the IX
fabric.
