Symptom:
Every time the system boots, the zeroconf route (169.254.0.0) is enabled. You manually disable it by turning off the firewall and remove the route with 169.254.0.0 / 255.255.0.0 using the route command.
Example output of the route with the zeroconf route enables would like similar to the following:
# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.15.50.0 * 255.255.252.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
Solution:
To disable the zeroconf route during system boot, edit the /etc/sysconfig/network file and add the following NOZEROCONF value to the end of the file:
NETWORKING=YES
HOSTNAME=localhost.localdomain
NOZEROCONF=yes
