   In your example, wouldn't turning off Client to Client also prevent
   RTRA from being reflected to RTRC or RTRD?
   The command "no bgp client-to-client reflection" doesn't specify who
   to not reflect to .... so it seems that it
   would turn off all reflection. If it turns off all reflection what
   is its purpose? I will do some research also..

   But you need to configure which are your clients on the same box!
   
   
   
   ie Halibi RTF - reflect routes between E and D. This is to allow E to
   receive routes from D and vice versa even though they're not meshed.
   
   
   
   The client-to-client reflection is more for if there's a number of
   clients who are also acting as 'servers' and they don't need to pass
   routes between them. ie RTA advertises routes to RTRB which reflects
   the routes to RTRC and RTRD. RTRC and RTRD also have RR clients E&F&G
   and H&J&I resp. If E&F&G doesn't need to know about H&J&I or vice
   versa but EFG and HJI need the routes from RTRA - turn off client to
   client reflection on RTRB.
   
   
   
   confused??

   The halabi book page 425:
   
    halabi tell us that where multiple route reflectors are configured
   inside the cluster,all
   
   router reflector need to be configured with a common cluster-ID.If
   RTE,RTF are all route reflector,
   
   so the rtf configuration is :
   
   router bgp 3
   
   no sy
   
   no bgp client-to-client reflection (what's this command do here?)
   
   neighbor RTE remote 3
   
   neighbor RTE route-reflector-client
   
   neighbor RTD remote 3
   
   neighbor RTD route-reflector-client
   
   bgp cluster-id 1000
   
   
   
   BUT I think ,if the rte and rtf are all rr,
   
   so the rtf config should be:
   
   router bgp 3
   no sy
   no bgp client-to-client reflection (what's this command do here?)
   neighbor RTE remote 3
   neighbor RTD remote 3
   neighbor RTD route-reflector-client
   bgp cluster-id 1000
   
   and rte config should be:
   
   router bgp 3
   no sy
   no bgp client-to-client reflection (what's this command do here?)
   neighbor RTF remote 3
   neighbor RTD remote 3
   neighbor RTD route-reflector-client
   bgp cluster-id 1000
   
   SO IS HALABI WRONG OR ME ?
   
   THANKS IN ADVANCE
