According to your first question: "1. Can you have route reflectors within a
confederation if the IBGP peers don't have a full mesh?" I am sure to answer
you: Yes!!!!!!
I have meet the same question when I studied in BGP.
And here is the example:
Router1======Router3======Router2
(Route Reflector)
Since all of the three routers are in the same confederation 65050. And the
"valid" AS is 200, they in AS 200 too, of course.
