Configuring a Default IPv6 Route
In the absence of router advertisements, you can add the default IPv6 router information
to the /etc/rc.config.d/netconf-ipv6 file. The routing configuration parameters
have an index value, [x], that groups the routing parameters together.
A sample netconf-ipv6 file entry is as follows:
IPV6_DESTINATION[0]="default"
IPV6_GATEWAY[0]="2001:db8::1"
IPV6_ROUTE_COUNT[0]="1"
IPV6_ROUTE_ARGS[0]=""
Configuring Anycast Addresses
Anycast addresses can be configured on the secondary interfaces only. To configure an
anycast address, edit the /etc/rc.config.d/netconf-ipv6 file to specify the
secondary interface name, IPv6 address, prefix length, secondary interface state and
interface flag. You must set the anycast keyword in the
IPV6_SECONDARY_INTERFACE_FLAG field to configure the address as an anycast
address.
Following is a sample /etc/rc.config.d/netconf-ipv6 file entry:
IPV6_SECONDARY_INTERFACE_NAME[2]="lan0:2"
IPV6_ADDRESS[2]="2001:db8::6"
IPV6_PREFIXLEN[2]="64"
IPV6_SECONDARY_INTERFACE_STATE[2]="up"
IPV6_SECONDARY_INTERFACE_FLAG[2]="anycast"
DHCPV6_ENABLE[2]=0
Ensure that you always set the DHCPV6_ENABLE field to 0. For more information on
specifying interface names for multiple interfaces, see Chapter 4 (page 46).
Tunneling
HP-UX 11i v3 provides several important changes to tunneling from in base (default)
HP-UX 11i v2 IPv6. These changes are also included in HP-UX 11i v2 PI (September
2004 release). Highlights of these changes are:
— Configured tunneling is point-to-point with an address assigned to both tunnel
endpoints. As a result, you can no longer use the route command to configure a
tunnel. You must use ifconfig and /etc/rc.config.d/netconf-ipv6, and
be aware that the tunneling parameters have changed.
— The HP-UX server can be configured as a router in both point-to-point configured
tunnels and in point-to-multipoint “6to4” tunnels. Prior to HP-UX 11i v2 PI (September
2004 release), the HP-UX 11i v2 node would only perform as a “6to4” host” not
as a “6to4” router. Parameters for “6to4” router configuration are in ifconfig
and in /etc/rc.config.d/netconf-ipv6.
— Automatic tunneling using the IPv4-compatible address is not supported.
