B.5.3 Configuring virtual interfaces with tagged VLAN (Logical IP takeover, Synchronous switching)

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

The xx and yy 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".

An example of configuring /etc/radvd.conf to use Linux server as an IPv6 router is described below. For details on /etc/radvd.conf, refer to radvd.conf(5) manual. Do not configure radvd on the server running NIC switching mode.

1) On /etc/sysconfig/network-scripts/ifcfg-ethX or /etc/sysconfig/network/ifcfg-ethX file (ethX refers to an interface name), define a statement allows to activate the entire interfaces during the system startup. The following is an example of ifcfg-eth0.

In example (/etc/sysconfig/network-scripts/ifcfg-ethX) of setting the following, operating system is an example of RHEL4. Please refer to "3.2.2 Network configuration" for the setting examples other than RHEL4.

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

DEVICE=eth0
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

2) When the system is RHEL, on /etc/sysconfig/network file, define a statement allows the system to load IPv6 module.

NETWORKING=yes
NETWORKING_IPV6=yes
IPV6TO4INIT=no

3) Create /etc/radvd.conf file and define the following on the interface radvd uses. Depending on the versions of radvd, you must define the kernel parameter (net.ipv6.conf.all.forwarding=1) on /etc/sysctl.conf file. For details on this configuration, see radvd.conf(5) or radvd(8) manual.

interface eth0
{
        AdvSendAdvert on;          # Sending router advertisements
        MinRtrAdvInterval 3;
        MaxRtrAdvInterval 10;
        prefix fec0:1::0/64        # Sending Prefix fec0:1::0/64 from eth0
        {
                AdvOnLink on;
                AdvAutonomous on;
                AdvRouterAddr on;
        };
};

4) Reboot the system. Make sure radvd process is running after rebooting the system.

[HOST-A]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/hosts file.

fec0:1::1       v6hosta1   # HOST-A Virtual IP (1)
fec0:2::1       v6hosta2   # HOST-A Virtual IP (2)
fec0:1::2       v6hostb1   # HOST-B Virtual IP (1)
fec0:2::2       v6hostb2   # HOST-B Virtual IP (2)
fec0:1::100     swhub1     # Primary Switch/HUB IP
fec0:1::101     swhub2     # Secondary Switch/HUB IP

1-2) Configure /etc/sysconfig/network-scripts/ifcfg-ethX (X is 0,1) file as follows.

In example (/etc/sysconfig/network-scripts/ifcfg-ethX) of setting the following, operating system is an example of RHEL4. Please refer to "3.2.2 Network configuration" for the setting examples other than RHEL4.
