  • Router ID
  • VPN domain ID

    When locating OSPF faults, you can run the display ospf brief command to view brief OSPF information.

Example

The actual command output varies according to the device. The command output here is only an example.

Table 1 Description of the display ospf brief command output
Item Description
OSPF Stub Router State Reason: Startup Synchronize

Reason why the Stub Router state is displayed. This state is displayed only when a stub router is restarting.
OSPF is in LSDB overflow status(remain time: 205s)

The maximum number of external routes in the OSPF LSDB is in the overload state (the remaining time of the overload timer is 205s).

When the number of external routes in the OSPF LSDB reaches or exceeds 90% of the maximum number, the following information is displayed:

OSPF LSDB is approaching overflow limit .

To configure the maximum number of external routes supported by the OSPF LSDB, run the lsdb-overflow-limit number command.
Router LSA stub links with cost 65535

The maximum cost 65535 is set for stub links in router LSAs. The function is enabled using the stub-router command.
Router ID conflict state
