When booting without a network cable plugged in

Hi,
I used openSUSE 12.3 and upgraded to 13.2.

openSUSE 12.3 is Set IP and shut down the system.
After booting without plugging in the network cable, IP was reflected normally.
(ifconfig eth0, ifconfig eth1)

but openSUSE 13.2 is Set IP and shut down the system.
After booting without a network cable plugged in, it will be out of IP state.
(ifconfig eth0 is UP BROADCAST MULTICAST)

Is there any difference when upgrading to 13.2?
Adding ‘LINK_REQUIRED = no’ to ifcfg-eth0 is the same.

I want to be able to boot IP without applying a network cable.
Thank you for your instructions.

In my experience (but maybe I didn’t pay special attention to 12.3, it was so long ago),
When you boot up, if your network interface is configured for DHCP it won’t be assigned a private network address, it’s typically null (no value) but if it has any value it would be a link-local address (starting with 169).

Are you sure your system wasn’t on standby or was configured with a static address?

BTW - The proper procedure upgrading would have been 12.3 > 13.1 > 13.2.
Skipping a version can have consequences.

And, since your upgrade have you updated your system at least once(It’s an important step)?
You should run the following in an elevated console
