For link-state IGPs, it is suggested that a site utilizing ULA
prefixes be contained either within one IGP domain or area. By
containing a ULA prefix to a single link-state area or domain, the
distribution of prefixes can be controlled.
I think it potentially could cause conflicts with the idea of using the
same subnet numbers as those used with a global prefix.
The language "it is suggested" was chosen to allow flexibility. As you
point out in large multi domain/area deployments there are reasons to do
it differently.

Or, to get this ID moving, remove both suggestions, and leave this
issue to be addressed somewhere else.
In my personal view, this would be the best course for now. Later on it
would be good to get feedback on how people deploy ULAs in operational
networks. For example, this might be a good activity for v6ops.
Actually, I would be surprised if there wasn't a lot of interest in
tracking deployment and operational experience.
I guess. It's a shame this point didn't come up during Last Call.
If we change something other than what the IESG asked us to change,
we are on the edge of a process problem. I though that lower-case
"suggested" was OK - it's much weaker than an official SHOULD, which
would certainly be a mistake for the reasons Mark gave.
