How to send syslog to multiple destinations?

[kelk (kin)]

I'm using logstash syslog module to send customized outputs to multiple destinations/port
I've done as below, but somehow only the 1st destination receives message.
Is there another format to have multiple syslog outputs?

output {
    syslog{
        host => "10.1.2.1"
        port => 514
        protocol => "tcp"
        appname => ""
        procid => ""
        sourcehost => "myhost"
    }
    syslog{
        host => "10.1.2.2"
        port => 514
        protocol => "tcp"
        appname => ""
        procid => ""
        sourcehost => "myhost"
    }
    syslog{
        host => "10.1.2.3"
        port => 10514
        protocol => "tcp"
        appname => ""
        procid => ""
        sourcehost => "myhost"
    }
}
