show ip ospf database

Shows OSPFv2 database information.

Syntax

show ip ospf database database-summary [ vrf vrfname ]
show ip ospf database external-link-state [ advertise index | extensive | link-state-id id | router-id router-id | sequence-number num ] [ vrf vrfname ]
show ip ospf database grace-link-state [ vrf vrfname ]
show ip ospf database link-state [ adv-router router-id | advertise index | asbr { asbr-id | adv-router router-id } | extensive | link-state-id id | network { net-id | adv-router router-id } | nssa { nssa-id | adv-router router-id } | router { router-id | adv-router router-id } | self-originate | sequence-number num | summary { id | adv-router router-id } ] [ vrf vrfname ]
show ip ospf database [ vrf vrfname ]

Parameters

database-summary
Displays how many link state advertisements (LSAs) of each type exist for each area, as well as total number of LSAs.
vrf name
Specifies the name of the VRF instance. If this option is not used, details for the default VRF are shown in the output.
external-link-state
Displays information by external link state, based on the following parameters:
advertise index
Displays the hexadecimal data in the specified LSA packet. The index parameter identifies the LSA packet by its position in the router‘s External LSA table. To determine an LSA packet‘s position in the table, enter the show ip ospf external-link-state command.
extensive
Displays LSAs in decrypt format. Do not use this parameter in combination with other display parameters because the entire database is displayed.
link-state-id id
Displays external LSAs for the LSA source that you specify.
router-id router-id
Displays external LSAs for the advertising router that you specify.
sequence-number num
Displays the External LSA entries for the hexadecimal LSA sequence number that you specify.
link-state
Displays the link state, based on the following parameters:
adv-router router-id
Displays the link state for the advertising router that you specify.
advertise index
Displays the hexadecimal data in the specified LSA packet. The index parameter identifies the LSA packet by its position in the router‘s external-LSA table. To determine an LSA packet‘s position in the table, enter the show ip ospf external-link-state command.
asbr
Displays autonomous system boundary router (ASBR) LSAs.
extensive
Displays LSAs in decrypt format. Do not use this parameter in combination with other display parameters because the entire database is displayed.
link-state-id id
Displays LSAs for the LSA source that you specify.
network
Displays either all network LSAs or the LSAs for a network that you specify.
nssa
Displays either all NSSA LSAs or the LSAs for a not-so-stubby area (NSSA) that you specify.
router
Displays LSAs by router link.
router-id router-id
Displays LSAs for the advertising router that you specify.
self-originate
Displays self-originated LSAs.
sequence-number
Displays the LSA entries for the hexadecimal LSA sequence number that you specify.
summary
Displays summary information. You can specify link-state ID or advertising router ID.
adv-router router-id
Displays the link state for the advertising router that you specify.
