Description of problem:

keepalived 2.1.5 in RHEL-8 does not allow to set weight 0 on real-servers

Version-Release number of selected component (if applicable):

keepalived-2.1.5-9.el8.x86_64

How reproducible:

• create /etc/keepalived/keepalived.conf with the following content (note weight is zero):

virtual_server 127.0.0.1 80 {
protocol TCP

real_server 127.0.0.1 81

}

• start keepalived:

• check IPVS configuration. You should see that real-server weight is 1, instead of 0:

1. ipvsadm -Ln
