Configuring OSPFv3
To configure OSPFv3, you must perform the following steps.
• Enable OSPFv3 globally.
• Assign OSPF areas.
• Assign device interfaces to an OSPF area.
The following configuration tasks are optional:
• Configure a virtual link between an Area Border Router (ABR) without a physical connection to a
backbone area and the device in the same area with a physical connection to the backbone area.
• Change the reference bandwidth for the cost on OSPFv3 interfaces.
• Configure the redistribution of routes into OSPFv3.
• Configure default route origination.
• Modify the shortest path first (SPF) timers.
• Modify the administrative distances for OSPFv3 routes.
• Configure the OSPFv3 LSA pacing interval.
• Modify how often the Brocade device checks on the elimination of the database overflow condition.
• Modify the external link state database limit.
• Modify the default values of OSPFv3 parameters for device interfaces.
• Disable or re-enable OSPFv3 event logging.
• Set all the OSPFv3 interfaces to the passive state.
Enabling OSPFv3
Before enabling the device to run OSPFv3, you must perform the following steps.
• Enable the forwarding of IPv6 traffic on the device using the ipv6 unicast-routing command.
• Enable IPv6 on each interface over which you plan to enable OSPFv3. You enable IPv6 on an
interface by configuring an IPv6 address or explicitly enabling IPv6 on that interface.
By default, OSPFv3 is disabled. To enable OSPFv3 for a default Virtual Routing and Forwarding (VRF),
you must enable it globally.
To enable OSPFv3 globally, enter the following command.
device(config)# ipv6 router ospf
device(config-ospf6-router)#
After you enter this command, the Brocade device enters the IPv6 OSPF configuration level, where you
can access several commands that allow you to configure OSPFv3.
Enabling OSPFv3 in a VRF
To enable OSPFv3 for a default Virtual Routing and Forwarding (VRF), enter a command such as the
following.
device(config-ospf6-router)# ipv6 router ospf vrf red
Syntax: [no] ipv6 router ospf vrf vrf-name
The vrf-name parameter specifies the name of the VRF in which OSPFv3 is being initiated.
