OSPF Status

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

See also

For more general dynamic routing status information, see Dynamic Routing Manager Status

The general form of the command to view OSPF state information is show route dynamic ospf <options>. Output includes all VRFs by default, but may be restricted to a single VRF by using show route dynamic ospf vrf <vrf-name> <options> instead. The list of options is the same in both cases.

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)

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.
