in which case I will need to configure " no-client-reflect " ,, As far as I know it's used if the clients are in full mesh and your using it so u will not reflect the same route to it , but if I have full mesh client at the first place why I am using route reflector and if the RR configured with this knob then what is the use of it ( RR )

If u r using full-mesh so no need to use RR. I will give u one scenario to use no-client-reflect when u have more than one client in the group and u don't want to reflect routes to specific neighbor from RR side, you could use this command at neighbor level

Thanks for your reply , this is what I understand but in the Description in the below link it say we use it in case if we have full mesh and RR to prevent sending redundant copy of the updates

Yes that's right (Include this statement when the client cluster is fully meshed) when the client is fully meshed so no need to send route advertisement from RR

Recently i used no-client-reflect for my migration project.
The scenarios is as follows:
1. I have existing network A with 2 RR & 21 RR-Clients routers where most of my customer connected to RR-Client.
2. I need to migrate all the customers from network A to network B.
3. Network B router running on full-mesh & in order to get the routes from network A i would need a peering session with RR in network A.
4. i configured no-client-reflector on RR to prevent the routing loop & sending of redundant route advertisements.

Can you please illustrate an example / scenario where we use this command ? Any practical example? Why on earth would some body have both the fully meshed routers in a cluster and a network with Route reflector operational concurrently? If at all there is migration from fully meshed network to a network with RR, what is the strategy of using this command No-client-reflect?
And by the way this is also a JNCIP question. I came across this command while studying JNCIP.

Actually you might use this knob in case if you need to reflect between BGP peers reside in different groups without reflecting within the group itself, for example your router has four IBGP sessions in two different groups (2 sessions peer group), two sessions with two IGW routers in group1 and remaining two with internal PE in group2 and you need to reflect internet routes received from IGW routers to the PEs without reflecting routes between the IGW routers in group1.
This is not doable with the default configuration due to the IBGP loop prevention mechanism, and in order to circumvent this you have to configure one of the groups (group1) with the cluster knob to act as RR, however you still need to use the no-client-reflect knob to disable reflection between the IGW routers.
