Table 8.3: CLI Display of OSPF Neighbor Information (Continued)

 

 

Field

Description

 

 

Pri

The OSPF priority of the neighbor. The priority is used during election of the Designated

 

Router (DR) and Backup designated Router (BDR).

 

 

State

The state of the conversation between the routing switch and the neighbor. This field can

 

have one of the following values:

 

• Down – The initial state of a neighbor conversation. This value indicates that there has

 

been no recent information received from the neighbor.

 

• Attempt – This state is only valid for neighbors attached to non-broadcast networks. It

 

indicates that no recent information has been received from the neighbor.

 

• Init – A Hello packet has recently been seen from the neighbor. However, bidirectional

 

communication has not yet been established with the neighbor. (The routing switch

 

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 – Communication between the two routers is bidirectional. This is the most

 

advanced state before beginning adjacency establishment. The Designated Router and

 

Backup Designated Router are selected from the set of neighbors in the 2-Way state or

 

greater.

 

• ExStart – The first step in creating an adjacency between the two neighboring routers.

 

The goal of this step is to decide which router is the master, and to decide upon the

 

initial Database Description (DD) sequence number. Neighbor conversations in this

 

state or greater are called adjacencies.

 

• Exchange – The routing switch is describing its entire link state database by sending

 

Database Description packets to the neighbor. Each Database Description packet has a

 

DD sequence number, and is explicitly acknowledged. Only one Database Description

 

packet can be outstanding at any time. In this state, Link State Request packets can

 

also be sent asking for the neighbor's more recent advertisements. All adjacencies in

 

Exchange state or greater are used by the flooding procedure. In fact, these

 

adjacencies are fully capable of transmitting and receiving all types of OSPF routing

 

protocol packets.

 

• Loading – Link State Request packets are sent to the neighbor asking for the more

 

recent advertisements that have been discovered (but not yet received) in the Exchange

 

state.

 

• Full – The neighboring routers are fully adjacent. These adjacencies will now appear in

 

router links and network link advertisements.

 

 

Neigh Address

The IP address of the neighbor.

 

 

Neigh ID

The OSPF router ID.

 

 

Ev

The number of times the neighbor’s state changed.

 

 

Opt

The sum of the option bits in the Options field of the Hello packet. This information is used

 

by HP technical support. See Section A.2 in RFC 2178 for information about the Options

 

field in Hello packets.

 

 

Cnt

The number of LSAs that need to retransmitted.
