Describes how to query the OSPF neighbor table on a router in the OSPF configuration of a router.

OSPF neighbor Table query on the R1 Router

 
 

  
  
R1 # sh ip ospf neighbor command for querying OSPF neighbor table
  
  
 
  
  
Neighbor ID Pri State Dead Time Address Interface
  
  
 
  
  
2.2.2.2 1 FULL/-00:00:35 199.99.1.2 Serial1/0
 
 

"Neighbor ID" indicates the route ID of the neighboring router, and the route ID is the unique identifier of the router in the OSPF network.

Pri router priority

The status of the State router is FULL.

Dead Time The Last Time Route information was learned

Address peer interface IP Address of the neighbor Router

Interface: connect the local Interface of the neighboring Router

Query the OSPF neighbor table on the R2 Router

 
 

  
  
R2#sh ip ospf neighbor  
  
  
 
  
  
Neighbor ID     Pri   State           Dead Time   Address         Interface  
  
  
 
  
  
199.99.2.2        1   FULL/  -        00:00:31    199.99.2.2      Serial1/1  
  
  
 
  
  
1.1.1.1           1   FULL/  -        00:00:39    199.99.1.1      Serial1/0 
 
 

"Neighbor ID" indicates the route ID of the neighboring router, and the route ID is the unique identifier of the router in the OSPF network.

Pri router priority

The status of the State router is FULL.

Dead Time The Last Time Route information was learned

Address peer interface IP Address of the neighbor Router

Interface: connect the local Interface of the neighboring Router

OSPF neighbor Table query on R3 Router

 
 

  
  
R3#sh ip ospf neighbor  
  
  
 
  
  
Neighbor ID     Pri   State           Dead Time   Address         Interface  
  
  
 
  
  
2.2.2.2           1   FULL/  -        00:00:37    199.99.2.1      Serial1/1 
 
 

"Neighbor ID" indicates the route ID of the neighboring router, and the route ID is the unique identifier of the router in the OSPF network.

Pri router priority

The status of the State router is FULL.

Dead Time The Last Time Route information was learned

Address peer interface IP Address of the neighbor Router

Interface: connect the local Interface of the neighboring Router

The process of querying the OSPF neighbor table on the vroospf is complete. I hope you can understand it. Next, we will introduce step 5 of router OSPF configuration: query the OSPF link status database on the router.

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 the basic configuration and connectivity test of OSPF in Router OSPF configuration.
6. Describes how to query the connection status database of ospf on a Router Based on the OSPF configuration of a router.
