I want to configure IPV6 on the system and not use some auto ipv6 config.
I have tried to use IPV6_AUTOCONF=no in interface script dose not affect 
anything.

ifcfg-eth0:
GATEWAY=192.168.1.254
IPV6INIT=no
IPV6_AUTOCONF=no
BROADCAST=192.168.1.255
BOOTPROTO=none
NAME=""
NM_CONTROLLED=yes
MACADDR=""
TYPE=Ethernet
DEVICE=eth0
NETMASK=255.255.255.0
MTU="1500"
IPADDR=192.168.11.1
NETWORK=192.168.11.0
ONBOOT=yes

The above file should have resulted an interface with only inet address 
but the result is:
eth0      Link encap:Ethernet  HWaddr XX
           inet addr:192.168.11.1  Bcast:192.168.1.255  Mask:255.255.255.0
           inet6 addr: fe80::7271:bcff:febd:c46b/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
