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:
• Configure a router ID or a loopback interface with an IPv4 address configured or OSPFv3 are
not enabled.
• 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.
NOTE
Sometimes OSPFv3 neighbor states are flapping when there are three or more sessions between a
Virtual ADX and an FESX or Cisco device. To overcome this issue, Please configure the ports in
different VLANs or VEs so that the Source MAC address for each VLANID becomes unique.
