Describes how to query the connection status database of ospf on a Router Based on the OSPF configuration of a router.

Query the OSPF link status database on the R1 Router

R1 # sh ip ospf database query the OSPF link status database

OSPF Router with ID (1.1.1.1) (Process ID 100)

The OSPF route ID describing R1 is 1.1.1.1, and the process ID is 100

Router Link States (Area 0)

Region "0" in the route link status database"

We have finished the process of querying the OSPF link status database on the vroospf. Next we will introduce the last step of router OSPF configuration: Result Analysis

1. Result Analysis of router OSPF Configuration
2. Basic description of router OSPF Configuration
3. Describes the basic interface configuration for router OSPF configuration.
4. Test interface connectivity for router OSPF Configuration
5. Describes how to query the OSPF neighbor table on a router in the OSPF configuration of a router.
6. Describes the basic configuration and connectivity test of OSPF in Router OSPF configuration.
