Native IPv6 with Internode and CentOS

This is a WIP. Notes so far.
At the moment, this results in an error from DHCPv6 Client when trying to assign an addrss to ppp200:
Feb 10 23:28:50 tank dhcp6c[1063]: transmit failed: Network is unreachable
Manually adding an address makes it work:
Feb 10 23:28:47 tank dhcp6c[1382]: request prefix is 2001:44b8:7206:d180::/60
