Use this command to display the OSPF link state database.

Syntax

show ip ospf database [area ospf area ID] [asbr-summary link-state-id] [external link-state-id] [network link-state-id] [nssa-external link-state-id] [router link-state-id] [summary link-state-id] database-summary [process process ID range] [vrf {vrf name | all}] [opaque-global link-state-id]

Parameters

area	Area ID.
`ospf area ID`	OSPF area ID in either: Decimal value. Range is 0–4294967295 IP address format
	OSPF area ID in IP address format.
`link-state-id`	(Optional) Specifies the link state identifier. Valid values are IP addresses.
router	Displays router (Type 1) link state advertisements in their detailed format. Router advertisements are originated by all routers.
opaque-global	Opaque global LSA. Displays all OSPF-remotely learned VNI/VTEP associations.
network	Displays network (Type 2) link state advertisements in their detailed format. Network advertisements are originated by designated routers.
summary	Displays summary (Type 3) link state advertisements in their original format. Summary advertisements are originated by ABRs.
asbr-summary	Displays Autonomous System Border Router (ASBR) summary (Type 4) link status advertisements in their detail format. ASBR-summary advertisements are originated by ABRs.
external	Displays external (Type 5) link state advertisements. Type 5 link state advertisements in their detailed format.
nssa-external	Displays nssa-external (Type 7) link state advertisements in their detailed format. Type 7 advertisements are originated by ASBRs.
database-summary	Displays a numerical summary of the contents of the link state database.
process `process ID range`	Process identification range. Range is 1–65535.
vrf `vrf name` \|all	The VRF name. Either a specific VRF name (maximum of 32 characters) or all to specify all all VRFs.

Defaults

If link-state-id is not specified, the specified type of database records appears for all link state IDs.

Mode

All command modes.

Output...	What it displays...
Advertising Router	Router ID of the router originating the link state record.
LS Age	Age (in seconds) of the link state record.
Options	Options associated with this link state record.
LS Type	Specifies the link state type for this link state record.
Link State ID	Link ID, which varies as a function of the link state record type, as follows: Net Link States—Shows the interface IP address of the designated router to the broadcast network. Router Link States—Shows the ID of the router originating the record. Summary Link States—Shows the summary network prefix. VNI/VTEP—Shows VXLAN VNI.
Advertising Router	Specifies the IP address of the router advertising this link state.
LS Seq Number	OSPF sequence number assigned to each link state record.
Checksum	Field in the link state record used to verify the contents upon receipt by another router.
Length	Link count of router link state records. This number is equal to, or greater than, the number of active OSPF interfaces on the originating router.
Network Mask	Specifies the network mask for this link state record.
TOS	Specifies the Type of Service (ToS) configured for this link state record.
Metric	Specifies the ToS metric value.
Forwarding Address	Specifies the forwarding IP address associated with this link state record.
External Route Tag	Specifies the external route tag assigned to this link state record.
Number of TOS metrics	Specifies the number of ToS metrics associated with this link state record.
Opaque Information	Shows OSPF-remotely learned VNI/VTEP associations.
