John,
The site local address starts with fec0::/10. So, if your last 64 bits is
derived from mac address or not, does it really matter for the site-local
address, as the defining factor is the first 10 bits.
See the following link:

Subject: re:ipv6 eui-64 address
OK I see my mistake, but that leads to another question. For this example
I'm
supposed to be configuring a site-local address. Inverting the u bit gives
it
a value of 0, which makes it global. Now I'm really confused
I'm wondering if this might be due to dynamips. I have f0/0 with a MAC
address of c200.0848.0000. That yeilds a eui-64 address of C000:8FF:FE48:0.
My understanding is that I should get an eui address of C200:8FF:FE48:0. not
C000:8FF:FE48:0 What happened to the 2. It shouldn't be the U bit because
that would change the value of C. Also any resources for IPv6 besides the
RFC's that you know of would be helpful
