OSPF Configuration Commands 197 Table 34 Output Description of the display ospf peer Command Field Description Mode Master/Slave mode formed by negotiation in exchanging DD packet Priority Priority of DR/BDR for neighbor election DR IP address of the interface of elected DR BDR IP address of the interface of elected BDR Dead timer expires in If no hello packet received from the peer within this interval, the peer 31 seconds will be considered to be invalid. Neighbor has been up Time of neighbor connection for 01:14:14 To view brief information for every peer, enter the following: display ospf peer brief OSPF Process 1 with Router ID 1.1.1.1 Neighbor Statistics Area ID Down Attempt Init 2-Way ExStart Exchange Loading Full Total 0.0.0.0 0 0 0 0 0 0 0 1 1 0.0.0.1 0 0 0 0 0 0 0 1 1 Total 0 0 0 0 0 0 0 2 2 Table 35 Output Description of the display ospf peer brief Command Field Area ID Down Attempt Init 2-Way ExStart Exchange Loading Full Description Area ID The initial state for OSPF to establish neighbor relation, which indicates that the OSPF router has not received the message from a certain neighbor router within a period of time. Enabled in the NBMA environment, such as Frame Relay, X.25 or ATM. It indicates that OSPF router has not received the message from a certain neighbor router within a period of time, but still attempts to send a Hello packet to the adjacent routers for their communications with a lower frequency. Indicates that the OSPF router has received a Hello packet from a neighbor router, but its IP address is not contained in the Hello packet. Therefore, a two-way communication between them has not been established. It indicates that a two-way communication between an OSPF router and a neighbor router has been established. DR and BDR can be selected in this state (or higher state) In this state, the router determines the sequence number of the initial database description (DD) packet used for data exchange, so that it can obtain the latest link state information. Indicates that the OSPF router sends DD packets to its neighbor routers to exchange link state information. In this state, OSPF router requests routes from the neighbor based on the updated link state information from neighbor routers and its expired information, and waits for response from neighbor routers. Indicates that database synchronization between the routers has been completed, and their link state databases are consistent. display ospf Syntax request-queue display ospf [ process-id ] request-queue
