The following section describes limitations of HP-UX 11i v2 IPv6 in TOUR 2.0 transport. These limitations also exist in base (default) HP-UX 11i v2 IPv6 transport.

setparms Not Enhanced for IPv6 Configuration

On HP-UX 11i v2, the setparms utility has not been enhanced to support IPv6 configuration.

Multihomed Host Limitation

In the absence of a router that is advertising prefixes, no more than one interface can be configured with IPv6 addresses on a host with multiple physical network interfaces. If multiple physical interfaces are configured with IPv6 addresses, and if there is no Router Advertisement received on any interfaces, the host has no way of knowing which interface to send packets out on. If packets are sent out on the interface that is on a different link than the destination node, then communication will fail. This configuration is neither recommended nor supported.

Distributed File System Limitations

NIS+, NIS, and NFS are currently not supported over 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.

Socket Caching Limitation

Socket caching does not support IPv6.
