Transport Optional Upgrade Release (TOUR) 2.5 Release Notes

Known Problems and Limitations

A host cannot identify the interface through which it has to send packets due to the

following reasons:

— A host has multiple physical network interfaces.

— A router on the link does not exist to advertise prefixes.

— The interfaces are configured with only link-local addresses.

If packets are sent through an interface that is on a different link than the destination

node, the communication fails. To overcome this limitation, the interfaces must be

configured with globally unique addresses or alternatively, a router that advertises

prefixes that can be added to the link.

• Distributed File System Limitation

Currently, NIS+, NIS, and NFS are not supported over IPv6.

• The setparms Utility Limitation

The setparms utility is not enhanced to support IPv6 configuration.

• The who -R, last -R, finger -R Commands Limitations

The who -R, last -R, and finger -R commands are not enhanced for IPv6. Following are

the observations when using these commands:

— The output of the commands who -R and last -R displays a truncated IP address

when IPv6 on TOUR 2.5 is installed and the user logs in remotely using an IP address

instead of a hostname.

—The finger -R command output displays a local host name, not the remote host

name, when IPv6 included in TOUR 2.5 is installed.

• SAM Limitation

SAM is not enhanced to support the tunneling enhancements available with TOUR 2.5.

To configure TOUR 2.5 tunneling, you must edit the /etc/rc.config.d/netconf-ipv6

file or use the ifconfig command.

HP-UX Mobile IPv6 Limitations
