Verifying OSPF Configuration

To display information about areas, interfaces, virtual links, redistribution, or OPSF in general, use the show commands listed in the following table:

show ip ospf	Displays OSPF status and general configuration parameters.
show ip ospf border-routers	Displays information regarding all or specified border routers.
show ip ospf ext-lsdb	Displays external Link State Advertisements from the areas to which the
	router is attached.

show ip ospf host show ip ospf lsdb show ip ospf neighbor show ip ospf redist-filter show ip ospf redist

Displays information on directly attached hosts.

Displays LSAs in the Link State Database associated with each area. Displays information on OSPF non-virtual neighbor routers Displays OSPF redistribution filter attributes.

Displays the specified redistribution instance that allows routes to be redistributed into OSPF.

show ip ospf routes	Displays OSPF routes known to the router.
show ip ospf virtual-link	Displays virtual link information.
show ip ospf virtual-neighbor	Displays OSPF virtual neighbors.
show ip ospf area	Displays either all OSPF areas, or a specified OSPF area.
show ip ospf area range	Displays all or specified configured area address range summaries for
	the given area.
show ip ospf area stub	Displays stub area status.
show ip ospf interface	Displays OSPF interface information.
show ip ospf restart	Displays the OSPF graceful restart related configuration and status.

For more information about the resulting displays form these commands, see the “OSPF Commands” chapter in the OmniSwitch CLI Reference Guide.

Examples of the show ip ospf, show ip ospf area, and show ip ospf interface command outputs are given in the section “OSPF Quick Steps” on page 1-4.
