Instructions are given for FreeBSD 5.2, Linux RedHat 8 and Windows XP in this chapter. Note the following:
The first step is to enable IPv6 on the operating system of N2 and N3 and verify it is working. The following sub-sections show how to do this for each operating system.
In FreeBSD, IPv6 is enabled by setting the ipv6_enable variable to yes in the /etc/rc.conf configuration file.
# cat /etc/rc.conf ipv6_enable=yes
While not necessary, it is simpler for this exercise to reboot FreeBSD after enabling IPv6.
Pinging to the loopback (::1) is a good way to see that basic IPv6 is working.
% ping6 ::1
Reply packets should now be seen on the screen.
To verify the IPv6 addresses on an interface, use ifconfig <interface_name>.
% ifconfig ...
