B.3.1 Example of the Single system

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

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

[HOST-A]

1) Setting up the system

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

192.168.70.1    host11  # HOST-A Physical IP (1)
192.168.71.1    host12  # HOST-A Physical IP (2)
192.168.80.1    hosta   # HOST-A Virtual IP
192.168.70.2    host21  # HOST-B Physical IP (1)
192.168.71.2    host22  # HOST-B Physical IP (2)
192.168.80.2    hostb   # HOST-B Virtual IP

1-2) Write the hostnames defined above in /etc/hostname."interface-name" files. If a file does not exist, create a new file.

- Contents of /etc/hostname.hme0

host11

- Contents of /etc/hostname.hme1

host12

1-3) Define the subnet mask in /etc/inet/netmasks file.

192.168.70.0    255.255.255.0
192.168.71.0    255.255.255.0
192.168.80.0    255.255.255.0

1-4) Create /etc/inet/ndpd.conf file and set the followings:

ifdefault AdvSendAdvertisements true  # Every interface sends a router advertisement.
prefix fec0:1::0/64 sha0              # sha0 sends Prefix "fec0:1::0/64".

In the Solaris 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.
For details on /etc/inet/ndpd.conf, refer to the Solaris manual.

1-5) Create /etc/hostname6.hme0 and /etc/hostname6.hme1 files as an empty file.

2) Reboot

Run the following command to reboot the system. Make sure hme0 and hme1 are enabled as IPv4/IPv6 interfaces after rebooting the system.

/usr/sbin/shutdown -y -i6 -g0

3) Creation of virtual interface

/opt/FJSVhanet/usr/sbin/hanetconfig create -n sha0 -m t -i 192.168.80.1 -t hme0,hme1
/opt/FJSVhanet/usr/sbin/hanetconfig create inet6 -n sha0 -m t -t hme0,hme1

4) Activation of virtual interface

/opt/FJSVhanet/usr/sbin/strhanet

[HOST-B]

1) Setting up the system

1-1) Define IP addresses and hostnames in /etc/inet/hosts file. Defined information is the same as for HOST-A.

1-2) Write the hostnames defined above in /etc/hostname."interface-name" files. If a file does not exist, create a new file.

- Contents of /etc/hostname.hme0

host21

- Contents of /etc/hostname.hme1

host22

1-3) Define the subnet mask in /etc/inet/netmasks file. Defined content is same as HOST-A.

1-4) Create /etc/hostname6.hme0 and /etc/hostname6.hme1 files as an empty file.
