load balancing using haproxing with 3 mqttbroker with different ports (no replies)

Hi,
My main goal is to distribute 8000 connections among 3 mqtt brokers
having capacity of 3000,3000,2000 respectively .I want to distribute it
in the following way;first 3000 connections would be served by 1st
broker ,then next 3000 connections by the next broker and so on .But I
do not want 1st 3000 connections tobe distributed to 3 brokers but 1st
3000 conections should be acted by 1st broker itself.So,could you
please tell me which configuration should i use in order to achieve
this scenario?My mode of transmission is Tcp.


Thanks,

Kushal
