MySQL replication

MySQL replication with binlog update.

We have two MySQL cluster

Cluster 1
Cluster 2

Cluster 1 is a master for Cluster 2 then from Cluster 2 we replicate to MySQL Enterprise.

Application is connected to cluster 1

In application we are using query like

INSERT INTO table (a,b,c) VALUES (1,2,3)
  ON DUPLICATE KEY UPDATE c=c+1;

This insert is populated correctly to Cluster 2, but from cluster 2 to Enterprise instance it is causing an error – duplicated entry. An update is not executed.
