Unlike the prehistoric IPv4 protocol which relies on DHCP servers to be able to communicate and do anything useful, the modern IPv6 protocol is much more self-sufficient and in tune with 2012.
Introducing IPv6 Stateless Address Autoconfiguration or SLAAC. Described in RFC 4862 SLAAC is a mechanism that:
“requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information and information advertised by routers”
In Apple terms; it’s like magic!
Configuring OSPFv3 is not very different from configuring OSPF for IPv4. It’s actually simpler and much cooler since it’s running on IPv6.
Either prepare a topology using GNSparser or use this one:
6to4 is a transition mechanism that allows modern IPv6 sites to communicate over a legacy IPv4 network, like The Internet. Just like other auto-tunneling techniques the IPv6 end-to-end connectivity is made possible by encapsulating the IPv6 datagrams inside IPv4 datagrams.
Auto-tunneling is a last resort method compared to dual-stack or native IPv6 support, but it can be used as a temporary solution for providing IPv6 connectivity. Just don’t expect kick-ass performance http://www.potaroo.net/ispcol/2010-12/6to4fail.html.
