B.2.1 Example of the Single system

This section describes an example configuration procedure of the network shown in the diagram below.

The xx in the figure below are assigned automatically by the automatic address configuration.

For the network configuration other than GLS, refer to "3.2.2 Network configuration".

1) Setting up the system

Configure the /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

Contents of /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1
BOOTPROTO=static
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

2) Reboot

Run the following command to reboot the system. After rebooting the system, verify eth0 and eth1 are enabled as an IPv6 interface using the ip command.

/sbin/shutdown -r now

3) Creating a virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create inet6 -n sha0 -m t -t eth0,eth1

4) Setting up IPv6 routers

Create /etc/radvd.conf file and set the following.

interface sha0
{
        AdvSendAdvert on;        # Sending router advertisements
        MinRtrAdvInterval 3;
        MaxRtrAdvInterval 10;
        prefix fec0:1::0/64      # Sending Prefix fec0:1::0/64 from sha0
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

Note

In the server that runs Fast switching mode, configure two or more router as IPv6 router. If the IPv6 router breaks down, it cannot use site-local address to communicate.
To prevent this, it is recommended to setup at least two IPv6 routers.
Depending on the version of radvd, kernel parameter(net.ipv6.conf.all.forwarding=1) must be defined in /etc/sysctl.conf file. For details on /etc/radvd.conf, refer to the radvd.conf(5), radvd(8) manual.

5) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now
