HP-UX IPv6 Transport Administrator's Guide (September 2004)

IPv6 Software and Interface Technology
Migrating from IPv4 to IPv6
Chapter 6 65
— Interface Flag: Specify interface flag. If set to “-private”, disable
stateless address autoconfiguration using prefixes received in router
advertisements. Default is “private”, the interface will autoconfigure
addresses using prefixes received in router advertisements.
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 68 of this guide.
IMPORTANT Starting with the HP-UX 11i v2 September 2004 release, automatic
tunnels with IPv4-compatible addresses are not supported. These were
supported in the base (default) HP-UX 11i v2 release.
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 September 2004 release.
Figure 6-1 Host-Host Configured Tunnel
Figure 6-1 illustrates a scenario where you can set up a configured
tunnel between Host A and Host B.
On Host A:
— Using ifconfig (ephemeral), enter:
IPv4
network
IPv4:10.13.2.2
Host A Host B
IPv4:192.168.1.1
IPv6: fe80::1
IPv6:fe80::2
