Any neighbor configured under the BGP group that has the cluster command is a client. Any neighbor configured under a different group is a non-client. Propagation rules are as follows:
1) routes from clients => RR => clients and non-clients2) routes from non-clients => RR => only clients. In this example:
group A
neighbor R1
neighbor R2
group B
neighbor R3
neighbor R4
cluster 2.2.2.2
group C
neighbor R5
neighbor R6
Only R3 and R4 are clients. Routes from either R3 or R4 will be reflected to all other routers.
Routes from R1, R2, R5, and R6 will only be reflected to R3, and R4.

Subject: BGP route reflection question
I have a couple of bgp internal groups, say group A (peer with A), group B (peer with B), group C (peer with C) configured on one router, In one of groups, say B, I configured cluster
b.b.b.b.
set protocols bgp group B cluster 2.2.2.2
The routes received from router A will be reflected to router C ?
I tested in a lab and seemed yes. But I like to make sure it is right.
thanks !!!
