3 BGP observations

I'd really appreciate any comments anyone can offer on the following 3
observations.

1) Confederations.
It appears that when BGP routes are learnt about networks within a local
confederation, they get given a local preference of 100. Is there any
reason for this?

2) Route Reflectors.
Unless I've been doing something wrong, it looks like the reflector 'server'
will only reflect routes to the 'client(s)' if it has the route - not only
in the BGP table (sh ip bgp), but must have the route in the routing table
(sh ip ro) which implies that there must be BGP/IGP sync (or BGP/IGP sync
turned off). Is this correct?

3) BGP command not anywhere on the CD...
neighbor x.x.x.x remove-private-AS

This command has been in the IOS since 10.3 but no command references have
anything on it. Admittedly, I am studying from home and have no connection
to CCO. Has anyone used this command? What's the difference between
'private' ASs and 'public' ASs?

thanks in advance

Simon (6 weeks to go!!!)
