Transport Optional Upgrade Release Transition Release Notes

In conformance with RFC 2893 (which obsoletes RFC 1933) configured tunnels are
pseudo-interfaces with associated addresses. Previously, when conforming to RFC 1933,
tunnels were implemented using special routing entries. The RFC 1933 implementation did
not allow addresses to be associated with tunnels and hence, routing protocol daemons were
not able to process tunnel information.
HP-UX Server can be Configured as a Router in a Point-to-Point Configured
Tunnel This feature was introduced in TOUR 2.0.
The transition patch PHNE_35351 (for HP-UX 11i v1) allows you to use the following
tunneling topologies:
•host to router
•host to host
• router to host
• router to router
Now, the HP-UX server can perform the role of the router in the tunnel configuration.
Previously, the HP-UX server would only perform the host role.
Specific configuration instructions on how to enable the HP-UX server for performing
tunneling in the role of the router is provided in the HP-UX IPv6 Transport Administrator's
Guide for TOUR 2.0.
IP6-in-IP6 and IP-in-IP6 Support This feature was introduced in TOUR 2.0.
The transition patch PHNE_35351 (for HP-UX 11i v1) supports two additional tunneling
types, IP6-in-IP6 and IP-in-IP6.
IP6-in-IP6 tunnel configuration enables transmission of IPv6 packets encapsulated in an IPv6
header. IP-in-IP6 tunnel configuration allows transmission of IPv4 packets encapsulated in
an IPv6 header.
IP6-in-IP tunnel configuration allows transmission of IPv6 packets encapsulated in an IPv4
header. IP6-in-IP is used in tunneling topologies where isolated IPv6 domains are
communicating across IPv4 networks.
HP-UX Server can be Configured as a "6to4" Router This feature was introduced in
TOUR 2.0.
The transition patch PHNE_35351 (for HP-UX 11i v1) allows the HP-UX server to perform
the role of a router in a "6to4" configuration. Previously, the HP-UX server was only able to
perform the role of a host in a "6to4" configuration.
