Route Reflection

Hi,

           +--R3
R1--R2--|
           +--R4

Let's say that all these routers are in a single AS.. R1 has some BGP routes
and is peering with R2.. Now R2 is a route reflector..It is peering with R3
and R4. Now R4 and R3 do not have any BGP routes that need to be sent to the
other BGP neighbors... Now if the route reflection between clients have been
asked to be disabled, do we now have to have peering between R4 and R3? I
would assume that since there is no routes that exist on either R3 or R4
that needs to get to each other, there is no need of full mesh peering. But
the general rule is if the reflection is suppressed I need to have a full
mesh..

Any thoughts on this?
