The route 9.1.1.0/24 is not available in the routing table of Switch C. 
BGP route reflector configuration 
Network requirements 
In Figure 94 , all s witches run BGP.  
•   Between Switch A and Switch B is an EBGP co nnection; between Switch C and Switch B, and 
between Switch C and Switch D are IBGP connections. 
•   Switch C is a route reflector with clients Switch B and...

BGP confederation configuration 
Network requirements 
In Figure 95 , to reduce IBGP connections in AS 200, split it into three sub-ASs: AS65001, AS65002, and 
AS65003. Switches in AS65001 are fully meshed.
