Here's what I use:

$ more /etc/sysconfig/network-scripts/ifcfg-eth0*
::::::::::::::
/etc/sysconfig/network-scripts/ifcfg-eth0
::::::::::::::
# Realtek|RTL-8139/8139C/8139C+
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
IPADDR=192.168.2.11
NETMASK=255.255.255.0
TYPE=Ethernet
::::::::::::::
/etc/sysconfig/network-scripts/ifcfg-eth0:1
::::::::::::::
TYPE=Ethernet
DEVICE=eth0:1
BOOTPROTO=none
NETMASK=255.255.255.0
ONBOOT=yes
IPADDR=192.168.2.9
USERCTL=no
PEERDNS=no
NETWORK=192.168.2.0
BROADCAST=192.168.2.255


The IPADDR, NETWORK and NETMASK will need setting for each 
interface/alias, but a GATEWAY setting is a property of a system, not of 
a particular interface, so it should only need to be set in one place.
