HP-UX IPv6 Transport Administrator's Guide for TOUR 2.0 (April 2004, rev 2)

IPv6 Software and Interface Technology
Migrating from IPv4 to IPv6
Chapter 7 75
Automatic tunnels are point-to-multipoint tunnels. The IETF is in the
process of deprecating automatic tunnels with IPv4-compatible address
in favor of “6to4”. For more information on “6to4”, refer to ““6to4” -
Connecting IPv6 Domains over IPv4 Clouds” on page 78 of this guide.
IMPORTANT Starting with TOUR 2.0, automatic tunnels with IPv4-compatible
addresses are not supported. These were supported in base (default)
HP-UX 11i v2.
Configured Tunnel IP6-in-IP Tunnel (Host-Host) Example
This section provides an example of how to configure a simple IP6-in-IP
configured tunnel between two dual stack hosts both running HP-UX 11i
v2 TOUR 2.0.
Figure 7-1 Host-Host Configured Tunnel
Figure 7-1 illustrates a scenario where you can set up a configured
tunnel between Host A and Host B.
On Host A:
— Using ifconfig (ephemeral), enter:
ifconfig iptu0 inet6 tunnel ip6inip fe80::1 fe80::2 tsrc
192.168.1.1 tdst 10.13.2.2 up
— Editing /etc/rc.config.d/netconf-ipv6 (permanent), add:
IPv4
network
IPv4:10.13.2.2
Host A Host B
IPv4:192.168.1.1
IPv6: fe80::1
IPv6:fe80::2
