peer groups inside a RR cluster ..any restrictions ????

HI EXPERTS,

I am unable to understand the following points from Cisco doc *
*

*
*

*Important Note:* Do not use peer groups if the clients inside a cluster do
not have direct iBGP peers among one another and the clients exchange
updates through the RR. If you configure peer groups, a potential withdrawal
to the source of a route on the RR transmits to all clients inside the
cluster. This transmission can cause problems.

The router subcommand *bgp client-to-client reflection* is enabled by
default on the RR. If you turn off BGP client-to-client reflection on the RR
and you make redundant BGP peering between the clients, you can safely use
peer groups.

why i cant use peer groups insider a RR cluster ?

thanks
