I am trying to setup a multi-master type of replication with each master having an additional slave using tungsten. As an example, lets say I have 4 hosts (A,B,C,D) and Hosts A and C are the Masters, with B being a slave to A and D being a slave to C.

With my current configuration, I will add data to A. This gets replicated to it's slave B and to the other master C with no issue. The same happens with I add data to C, its slave D gets updated and the other master A gets updated. The problem is when A gets updated, D will not see the changes. I do not want A to update D, but rather have D get all of the updates from C, which would also have B get all of it's updates from A.

Here is the configuration script I have been working on.

MASTER1='master1-ca' #<-- 'A' from example
MASTER2='master2-va' #<-- 'C' from example
SLAVE1='slave1-ca'   #<-- 'B' from example
SLAVE2='slave2-va'   #<-- 'D' from example

./tools/tpm configure defaults  \
    --reset \
    --replication-user=tungsten \
    --replication-password=password \
    --home-directory=/home/tungsten/PCS_DB \
    --datasource-mysql-conf=/etc/mysql/my.cnf \
    $( cat ./cookbook/security.options ) \
    --start
 
./tools/tpm configure PCS_Multi \
    --masters=$MASTER1,$MASTER2 \
    --master-services=west,east \
    $( cat ./cookbook/security.options ) \
    --topology=all-masters

./tools/tpm configure west \
    --hosts=$MASTER1,$SLAVE1 \
    --slaves=$SLAVE1 \
    $( cat ./cookbook/security.options ) \
    --master=$MASTER1 

./tools/tpm configure east \
    --hosts=$MASTER2,$SLAVE2 \
    --slaves=$SLAVE2 \
    $( cat ./cookbook/security.options ) \
    --master=$MASTER2

./tools/tpm install

I have been looking through documentation and tutorials for a few days now and can't seem to figure out this last piece. I have tried to setup a relay from $MASTER1 to $SLAVE1 but since there is not a lot of documentation on setting up a relay (at least from what I could find) I do not know if I am doing it correctly (or if I should even be doing that in the first place).
