Chapter 8. Support for IPv6
Internet Protocol version 6 (IPv6) is an extension over the current IPv4 protocol.
IPv6 features support for 128 bit address as opposed to the 32 bit address
supported by IPv4. Except the change in address format, no other configuration
changes are required for IPv6 in the Community Console.
The difference between IPv4 and IPv6 configuration is a change in IP address or
URL format.
v If you are using the IPv4 protocol then write the address as in this example:
v If you are using the IPv6 protocol then write the IP in brackets ('[ 'and ']') as in
v If you are using the IPv6 protocol and an HTTP address then write the IP within
v If it is IPv6 and FTP address then write the IP within the square brackets ('[' and
Enabling tunneling IPv6 over IPv4
The IPv6 protocol cannot be used throughout the entire Internet so you must
encapsulate IPv6 packets within IPv4 and "tunnel" through networks where only
IPv4 is available.
RHEL Linux 3
About this task
To enable tunneling on an RHEL Linux 3 platform, follow the steps below:
1. Login as the Root user.
2. Add the line add - NETWORKING_IPV6=yes to the file etc/sysconfig/network.
3. Save the file and exit.
4. Add the following lines to the file etc/sysconfig/network-scripts/ifcfg-
5. Save the file and exit.
6. Issue ifconfig from the command prompt.
The system automatically generates an IPv6 address. Use this address for
configuring receivers and destinations in WebSphere Partner Gateway.
Windows 2003/XP
To configure IPv6 on a Windows 2003/XP system, follow the Microsoft guidelines
