How do I disable the zeroconf route so that the system will boot without the 169.254.0.0 / 255.255.0.0 route?
by Cynthia Davis
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

Additional Information:
Find out more about zeroconf at http://www.zeroconf.org/.

Solution? Leave it as it is or delete it :) It shouldn't make any problem
It's a local block of ip addresses and don't get routed.

Cheers,

PS: But perhaps dhcpcd or pump is running in background on due some
miss configuration?

I had such a experience with SuSE on a server with two network interface. While only one of them was connected to the lan with a fixed IP, the other was configured by YaST to get it's IP from a DHCP server.


I too am on SuSE. One IP is my LAN IP but the SuSE box is the DHCP server itself. But many of my friend have seen this on their RedHat servers.
169.254.0.0/16 dev eth0  scope link

Their machines had only 1 network card and had fixed IPs.

What is the solution to this?
