I am working in bare metal environment trying to setup HA loadbalancing using keepalived. When I try to ping the VIP which I given in keepalived config file from other machines in the same network its not reachable, but when I stop keepalived in one of the machines, the other becomes master and IP address is assigned automatically.

keepalived configuration 

vrrp_instance VI_PUB
{
        interface ens34
        state MASTER
        virtual_router_id 52
        priority 101
        virtual_ipaddress
        {
                192.167.3.54
        }
        track_interface
        {
                ens34
        }
}
virtual_server 192.167.3.54 8081
{
        delay_loop 4
        lb_algo sh # source hash
        lb_kind NAT
        protocol TCP
        real_server 172.16.3.23 8080
        {
                weight 1
                TCP_CHECK
                {
                        connect_timeout 15
                        nb_get_retry 3
                        delay_before_retry 2
                }
        }
        real_server 172.16.3.24 8080
        {
                weight 1
                TCP_CHECK
                {
                        connect_timeout 15
                        nb_get_retry 3
                        delay_before_retry 2
                }
        }
}

any help would be appreciated..!

I guess that

ip addr show | grep global

will show that your virtual address is

192.167.3.54/32

/32 is usually not the desired result, therefore you should add e.g. /24:

virtual_ipaddress {
  192.167.3.54/24
}
