IPv6 Configuration Guide K/KA/KB.15.15

interface loopback
Executed at the global or deeper configuration level to assign an IPv4 address
to a loopback interface on the routing switch.
For more information, see "Loopback Interfaces" in the latest Basic Operation
Guide.
Enabling IPv6 Routing
Syntax:
[no] ipv6 unicast-routing
Executed at the global configuration level to enable IPv6 routing on the routing
switch.
Default: Disabled
The no form disables IPv6 routing. (Global OSPFv3 routing must be disabled before
you disable IPv6 routing.)
Example 128 Enabling IPv6 Routing
HP Switch(config)# ipv6 unicast-routing
Enabling global OSPFv3 routing
Syntax:
router ospf3 [ enable | disable ]
The router ospf3 command executed alone puts the routing switch into ospf3
context. The keyword options enable or disable OSPFv3 on the routing switch.
This command allows you to configure OSPFv3 before activating it on the routing
switch. Global IPv6 unicast-routing must be enabled before executing this
command.
Default: Disabled
NOTE: If you disable OSPFv3, the switch retains all the configuration information
for the disabled protocol in flash memory. If you subsequently restart OSPF, the
existing configuration will be applied.
Example 129 enable global OSPFv3 routing
HP Switch(config)# router ospf3 enable
HP Switch(ospf3)#
Assigning the routing switch to OSPFv3 areas
After you globally enable OSPFv3 on the routing switch, use this command to create one or more
OSPFv3 areas within your autonomous system (AS).
A routing switch can belong to one area or to multiple areas. Participation in a given area requires
configuring one or more VLANs and assigning each to the desired area.
• If you want the VLANs configured on the routing switch to all reside in the same area, you
need to configure only that one area. (In this case, the routing switch would operate as an
internal router for the area.)
• If you want to put different VLANs on the routing switch into different areas, you need to
re-execute this command for each area. (In this case, the routing switch operates as an ABR
for each of the configured areas.)
