[lvs-users] real_server on the same machine where keepalived runs

[dousti <dousti@xxxxxxxxx>]

Hi,

I have two hosts (10.175.151.157/22 and 10.175.151.158/22) that run a udp
service. In order to provide HA, I'm using keepalived (10.175.148.242/22) on
these two hosts. This is the conf of one of the hosts (the other one is
similar (with necessary changed):

vrrp_instance VI_1 {
        interface eth0
        state MASTER
        virtual_router_id 51
        priority 101
        authentication {
            auth_type PASS
            auth_pass PASS123
        }
        virtual_ipaddress {
                10.175.148.242
        }
}

virtual_server 10.175.148.242 4342 {
        delay_loop 30
        lb_algo wrr
        lb_kind DR
        protocol UDP

        real_server 10.175.151.157 4342 {
                weight 1
                MISC_CHECK {
                        misc_path /tmp/nc0.sh
                        }
        }
        real_server 10.175.151.158 4342 {
                weight 100
                MISC_CHECK {
                        misc_path /tmp/nc0.sh
                        }
        }

}

However the packets destined for 10.175.148.242:4342 do not seem to make it
to any of the two servers. My question, can keepalived run on the same hosts
as where the real_server runs? I even tried lb_kind NAT and it doesn't seem
to be working.

Thanks for the help.
