Thanks for infos :-)
But for my understanding what is wrong/missing with site-local addresses definitions in RFC 2373 IPv6 Addressing Architecture:
"
Site-Local Unicast Addresses 1111 1110 11 1
Site-Local addresses are designed to be used for addressing inside of a site without the need for a global prefix.
Routers must not forward any packets with site-local source or destination addresses outside of the site."
I conclude from this RFC that i can use FEE0::/10 for a private network. I want of course a global communication inside a private network then i will allow routing (IGP) inside the network.
Any experiences of using v6 site-local addresses?

There is a builtin private address for IPv6. But it has different usage
than IPv4 private address:
- Each IPv6 configured interface has its own private address.
- This address is local for a particular link therefore it is
called link-local address.
- This link local address is used for local communication only
The address space is: fe80::/10
You should not expect address translation for ll (i.e link local)
addresses. If you need global communication you should use global IPv6
address. There are plenty of them and you should not expect to run out of
them.
There was some idea to provide site-local addresses, but it is being
deprecated by IETF, since not used/no defined properly the semantics.
I hope this helped.
