Exactly like any other global-scope IPv6 address. They just work. (I speak
from experience.)
How do I tell my router that the ULAs on the home side of the router are
different from ULAs on the cableco side?
Your ULAs are all in your ULA /48 prefix. I'm not clear why the cableco would
be using ULAs, but if they do, those address will be in the cableco's ULA /48.
No confusion is possible, and as a border router, it SHOULD drop outbound
packets with source addresses in your ULA /48.
If you want static addresses on your servers, it's no different from any
other static address. But maybe I am not understanding your concern.
If I knew I had an address range that held still, I would use DHCPv6 and see
how many of my devices handle it. What happens if I have ULA addresses
handed
out by DHCPv6 and global addresses from SLAAC? Do I have to turn off SLAAC?
In the router advertisements, the prefix information option for the ULA prefix
would need its A flag turned off.
(If this stuff is all written down somewhere, I would be thrilled to get
the reference.)
This is more for v6ops or even ipv6-ops(_at_)lists(_dot_)cluenet(_dot_)de. To
be honest I
don't know if any of the IPv6 books covers this stuff in detail.
