Keepalived setting both nodes as master

Hi,

I am running keepalived 1.3.2 on CentOS 6.8. I am setting up HA load
balancer HAProxy setup. My configs are as below

Master Server ----

cat keepalived.conf
global_defs {
# Keepalived process identifier
#lvs_id haproxy_DH
}
# Script used to check if HAProxy is running
vrrp_script check_haproxy {
script "/usr/bin/killall -0 haproxy"
interval 2
weight 2
}
# Virtual interface
# The priority specifies the order in which the assigned interface to take
over in a failover
vrrp_instance VI_01 {
state MASTER
interface eth0
virtual_router_id 51
priority 200
# The virtual ip address shared between the two loadbalancers
virtual_ipaddress {
172.16.0.75/32
}
track_script {
check_haproxy
}
}
