Showing OSPF Information

Table 3-11 Field Descriptions for show ospf neighbors Command (continued)

Field

Description

 

 

Prio

The router priority of the neighboring router. Contained in the

 

neighbor’s hello packets, this value is used by OSPF to select the

 

designated router for the attached network.

 

 

State/Dr

The state of a conversation being held with a neighboring router.

 

The following states are listed in order of their progression.

 

• Down - The initial state of a neighbor conversation. The

 

Down state indicates that the CSS has received no recent

 

information from the neighbor.

 

• Init - In this state, the CSS has seen a hello packet from the

 

neighbor. However, the CSS has not established bidirectional

 

communication with the neighbor (the router itself did not

 

appear in the neighbor’s hello packet). All neighbors in this

 

state (or higher) are listed in the hello packets sent from the

 

associated interface.

 

• 2-Way - In this state, communication between the two routers

 

is bidirectional. The designated router is selected from the set

 

of neighbors in state 2-Way (or greater).

 

• ExStart - This is the first step to create an adjacency between

 

the two neighboring routers. The goal is to decide which

 

router is the master, and to determine the initial Database

 

Description (DD) sequence number. Neighbor conversations

 

in this state (or greater) are called adjacencies.
