Assigning ipv6 to bonding interface - getting old as well as changed ipv6 in ifconfig output

Hi,

I have created a bonding bond1 interface with 6 Eth , mode=4. Recently i have changed my old ipv6 to new one and tried to restart as well as reload network service. Post which i can see old as well as changed ipv6 in ifconfig command output. Below are few files and command output for your reference :

Code:

# cat /etc/sysconfig/network-scripts/ifcfg-bond1
DEVICE=bond1
IPADDR=x.x.x.x
NETMASK=x.x.x.x
#GATEWAY=x.x.x.x
IPV6INIT=yes
IPV6ADDR=xxxx:xxxx:abcd:xxxx:xx:xx:xx:xxx
IPV6_DEFAULTGW=xxxx:xxxx:abcd:xxxx:xx:xx:xx:xxx
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
BONDING_OPTS="mode=4 miimon=100 xmit_hash_policy=1"
MTU=9000

where abcd is the correct and new ipv6 address which i should see in ifconfig command output , but post network restart and reload i can see below output where efgh which was old ipv6 address :

Code:

# ifconfig bond1
bond1     Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx
          inet addr:xx.xx.xx.xxx  Bcast:xx.xx.xx.xxx  Mask:xxx.xxx.xxx.xxx
          inet6 addr: xxxx:xxx:abcd:xxx:xxxx:xxxx:xxxx:xxx/64 Scope:Global
          inet6 addr: xxxx::xxxx:xxxx:xxxx:xxxx/64 Scope:Link
          inet6 addr: xxxx:xxx:efgh:xxx:xx:xx:xx:xxx/64 Scope:Global
          UP BROADCAST RUNNING MASTER MULTICAST  MTU:9000  Metric:1
          RX packets:9038660506 errors:0 dropped:0 overruns:0 frame:0
          TX packets:12779501600 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:619072218642 (576.5 GiB)  TX bytes:15842973892775 (14.4 TiB)

please let me know what needs to be done in order to only reflect new 'abcd' ipv6 in ipconfig command output ?

protocols

protocols(4)							   File Formats 						      protocols(4)

NAME

       protocols - protocol name database

SYNOPSIS

       /etc/inet/protocols

       /etc/protocols

DESCRIPTION

       The  protocols  file   is a local source of information regarding the known protocols used in the DARPA Internet. The protocols file can be
       used in conjunction with or instead of other protocols sources, including the NIS maps ``protcols.byname'' and "protocols.bynumber" and the
       NIS+ table ``protocols''. Programs use the getprotobyname(3SOCKET) routine to access this information.

       The protocols file has one line for each protocol. The line has the following format:

	 official-protocol-name protocol-number aliases

       Items  are separated by any number of blanks and/or TAB characters. A `#' indicates the beginning of a comment; characters up to the end of
       the line are not interpreted by routines which search the file. Protocol names may contain any  printable  character  other  than  a  field
       delimiter, NEWLINE, or comment character.

EXAMPLES

	 ipv6-icmp   58  IPv6-ICMP   # IPv6 internet control message protocol
	 ipv6-nonxt  59  IPv6-NoNxt  # No next header extension header for IPv6
	 ipv6-opts   60  IPv6-Opts   # Destination Options for IPv6
