Re: nopreempt not working - Keepalived 1.2.15

Starting to see the light at the end of the tunnel....It appears it is a
timing issue...keepalived is not receiving the VRRP packers , immediately
even after network service has started...
If i delay the start keepalived for a bit after startup then behavior is as
expected.....
