Here is what I have on a RHEL5 system with no issues:

ifcfg-eth0:0:

DEVICE=eth0:0
BOOTPROTO=static
ONBOOT=yes
IPADDR=130.111.16.171
NETMASK=255.255.255.0
NETWORK=130.111.16.0
NAME=eth0:0


You might want to get rid of your "TYPE" entry on the alias interface
as well as the IPV6INIT and USERCTL. They get inherited from the
parent interface. I'd start your alias interface at eth0:0 too.

Let us know if that helps.
