Configuring IPv6 on Linux
Red Hat Enterprise Linux and SUSE Linux Enterprise Server already
have the proper IPv6 tools installed, including the /sbin/ip command.
This section explains how to configure IPv6 stationary IP addresses on
these systems.
Enabling IPv6 on Red Hat Linux
Add the following lines to /etc/sysconfig/network:
NETWORKING_IPV6=yes # Enable global IPv6 initialization
IPV6FORWARDING=no # Disable global IPv6 forwarding
IPV6_AUTOCONF=no # Disable global IPv6 autoconfiguration
IPV6_AUTOTUNNEL=no # Disable automatic IPv6 tunneling
Adding persistent IPv6 Addresses on Red Hat Linux
This can be done by modifying the system configuration script, for
example, /etc/sysconfig/network-scripts/ifcfg-eth1:
DEVICE=eth1
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.10
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes
IPV6INIT=yes
IPV6ADDR=3ffe:ffff:0000:f101::10/64
IPV6ADDR_SECONDARIES=fec0:0:0:1::10/64
IPV6_MTU=1280
