[c-nsp] IPv6 Unique Local Address Routing Issue

[Mack McBride]

If you are using ULA please be sure to use the correct procedure to generate a /48 and register the /48 subnet with SixXS.  This keeps ULA unique.
Having added that caveat, unless there is a compelling reason you should use GUA addresses.
A /48 of GUA space is easy to get, usually the default minimum allocation from an upstream.
It provides 65536 subnets.  Dot1q only supports 4096 subnets per switching environment.

RFC6296 provides the spec for NTPv6 and recommends AGAINST NAT.
This is probably the only RFC that standardizes something while recommending that it never be used.

Subject: [c-nsp] IPv6 Unique Local Address Routing Issue

Hi Experts,
Anybody have the experience about IPv6 ULA deployment?
I know this kind of address is used within a site, can well done the intra-site communication, just like the private addresses in IPv4.
I have one question about ULA, since ULA is used as local communication, if my site need to internet access, how come it translate to global IPv6 address?

Will appreciate for any comments.

Best Regards,
Hu Xu
