We tried Fred's procedure some 4 years ago within 6NET: http://www.6net.org/publications/deliverables/D3.6.2.pdf The 'prefix schizo' actually worked out quite well. The routing changes and multi-refix links generally behaved as expected. Address selection did its thing. The basics worked as advertised. The complexity is of course not in the routing and hosts, it's as pointed out in the firewalls and similar devices (yours and more importantly other people's) for which new capabilities of IPv6 can't help. We captured some of these thoughts at the time in http://tools.ietf.org/html/draft-chown-v6ops-renumber-thinkabout-05 and since then Brian Carpenter has produced a much more up to date and rounded set of thoughts in http://tools.ietf.org/html/draft-carpenter-renum-needs-work-03 We're far from a magic button press. In smaller networks RFC4192 is workable, but the larger and more complex the network/site, there's still so many open issues that it's completely understandable the people will want PI. -- Tim
