Transport Optional Upgrade Release (TOUR) 2.0 Release Notes

Limitations

This section includes information on the limitations that exist for HP-UX 11i v2 TOUR 2.0

components.

IPv6 Transport Limitations

The limitations of IPv6 included in HP-UX 11i v2 TOUR 2.0 are as follows:

• Multihomed Host Limitation

In the case where a host has multiple physical network interfaces, and there is no router

on the link advertising preﬁxes, if the interfaces are conﬁgured with only link-local

addresses, the host cannot identify the interface through which it has to send packets. 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 could 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 has not been enhanced to support IPv6 conﬁguration.

• Socket Caching Limitation

Socket caching does not support IPv6.

• SAM Limitation

SAM has not been enhanced to support the tunneling enhancements available with TOUR

2.0. TOUR 2.0 tunneling conﬁguration must be done by editing the

/etc/rc.config.d/netconf-ipv6 ﬁle or by using the ifconfig command.

Mobile IPv6 Limitations

Currently there are no speciﬁc HP-UX Mobile IPv6 A.01.00 limitations to document.

PPPoE/v6 Limitations

Currently there are no speciﬁc PPPoE/v6 limitations to document.
