RE: Question about BGP and setting local preference

Ok, I've turned off the local pref, R1 can see the routes from BB1 and the
routes from BB2 via R3. R2 can also see all of the routes, R2 is also
configured as a RR for R1, R3, R4. R3 and R4 only see the routes that are
coming in from the eBGP connection between R3 and BB2. BTW R2 is directly
connected to R4.

BB1----R1 --------R2-----R3----BB2
                  |
                  R4

I've tried to research this thing as much as possible, it's just not working
the way I expected it to.

Peter.

Check on R1 and see if there are prefixes from both ends and they are
participating in the bestpath selection.

I would expect to see the prefixes from both ends of the AS actually.
But if you do a show ip bgp on R1, that should tell us why I think...
