OSPF Status¶
TNSR supports several commands to display information about the OSPF daemon configuration and its status.

For more general dynamic routing status information, see Dynamic Routing Manager Status
Configuration Information¶
To view the OSPF configuration:
tnsr(config)# show route dynamic ospf config
interface GigabitEthernet3/0/0
ip ospf area 0.0.0.0
exit
interface TenGigabitEthernet6/0/0
ip ospf area 0.0.0.0
ip ospf cost 10
exit
router ospf
ospf router-id 10.2.0.1
passive-interface GigabitEthernet3/0/0
Status Information¶
To view the OSPF database:
tnsr(config)# show route dynamic ospf database
OSPF Router with ID (10.2.0.1)
Router Link States (Area 0.0.0.0)
Link ID ADV Router Age Seq# CkSum Link count
10.2.0.1 10.2.0.1 129 0x80000005 0x6808 2

Additional more specific information is available by adding a keyword onto the
end of the command show route dynamic ospf database <name>
where <name>
is one of the following choices:
- asbr-summary:
Autonomous System Boundary Router (ASBR) database summary.
- external:
External link state information.
- max-age:
Link State Advertisement (LSA) entries in MaxAge list.
- network:
Network link states.
- nssa-external:
Not-so-stubby-area external link states.
- opaque-area:
Link area Opaque-LSA.
- opaque-as:
Link AS Opaque-LSA.
- opaque-link:
Link local Opaque-LSA.
- router:
Router link states.
- self-originate:
Link states originated from this router.
- summary:
Network summary link states.
