Link state advertisement types for OSPFv3

NOTE

You are required to configure a router ID when running only IPv6 routing protocols.

Link state advertisement types for OSPFv3

OSPFv3 supports the following types of LSAs:

• Router LSAs (Type 1)

• Network LSAs (Type 2)

• Interarea-prefix LSAs for ABRs (Type 3)

• Interarea-router LSAs for ASBRs (Type 4)

• Autonomous system external LSAs (Type 5)

• Link LSAs (Type 8)

• Intra-area prefix LSAs (Type 9)

For more information about these LSAs, refer to RFC 2740.

Configuring OSPFv3

To configure OSPFv3, you must do the following:

• Enable OSPFv3 globally.

• Assign OSPF areas.

• Assign router interfaces to an OSPF area.

The following configuration tasks are optional:

• Configure a virtual link between an ABR without a physical connection to a backbone area and

the Brocade 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 router interfaces.

• Disable or re-enable OSPFv3 event logging.

Enabling OSPFv3

Before enabling the Brocade device to run OSPFv3, you must do the following:
