B.5.4 Configuring virtual interfaces with tagged VLAN (Logical IP takeover, Asynchronous 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".

[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     # Switch/HUB1 IP
fec0:2::100     swhub2     # Switch/HUB2 IP

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

Note

The following setting example (/etc/sysconfig/network-scripts/ifcfg-ethX) is for RHEL5. For details, see "3.2.2 Network configuration".

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

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

DEVICE=eth1
BOOTPROTO=static
HWADDR=XX:XX:XX:XX:XX:XX
HOTPLUG=no
ONBOOT=yes
TYPE=Ethernet

1-3) Configure /etc/sysconfig/network-scripts/ifcfg-ethX.Y (X is 0,1. Y is 1,2) file as follows.

Contents of /etc/sysconfig/network-scripts/ifcfg-eth0.1
DEVICE=eth0.1 BOOTPROTO=static ONBOOT=yes
Contents of /etc/sysconfig/network-scripts/ifcfg-eth0.2
DEVICE=eth0.2 BOOTPROTO=static ONBOOT=yes
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1.1
DEVICE=eth1.1 BOOTPROTO=static ONBOOT=yes
Contents of /etc/sysconfig/network-scripts/ifcfg-eth1.2
DEVICE=eth1.2 BOOTPROTO=static ONBOOT=yes

1-4) 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
VLAN=yes

2) Reboot

Run the following command and reboot the system. After rebooting the system, verify eth0.1 and eth1.2 is enabled using ifconfig command.

/sbin/shutdown -r now

3) Creating of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create inet6 -n sha0 -m d -i fec0:1::1/64 -t eth0.1,eth1.1
/opt/FJSVhanet/usr/sbin/hanetconfig create inet6 -n sha1 -m d -i fec0:2::1/64 -t eth1.2,eth0.2

4) Setting up the HUB monitoring function

/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha0 -p fec0:1::100 -b off
/opt/FJSVhanet/usr/sbin/hanetpoll create -n sha1 -p fec0:2::100 -b off

5) Setting up the Standby patrol monitoring function

Please define only one Standby patrol monitoring function.

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha2 -m p -t sha0

6) Reboot

Run the following command and reboot the system.

/sbin/shutdown -r now
