ip address lost after reboot
 

i use iproute2 utility to configure my FC3 NIC.all thing work fine but after rebooting the machine all ip address configuration losts.i didn't find some configuration file like ifcfg-ethx that used by old ifconfig work for iproute2.
how i can save my iproute2 configuration so that any network service restart or machine reboot dont change my config ?

The iproute2 documentation covers this fairly well.

You will basically cut and paste a few new scripts for yourself.
