Interface Status
This page displays the OSPF interface status table. It is used to provide the OSPF interface status information.
Figure 20-2.4: OSPF Interface Status
Parameter descriptions
:
Interface
: Interface identification.
Interface Address
: IPv4 network address.
Area ID
: The OSPF area ID.
Router ID
: The OSPF router ID.
State
: The state of the link.
DR ID
: The router ID of DR. Each broadcast and NBMA network that has at least two attached routers has a DR.
The DR generates an LSA for the network and has other special responsibilities in the running of the protocol.
The DR is elected by the Hello Protocol.
DR Address
: The IP address of DR.
BDR ID
: The router ID of BDR.
BDR Address
: The IP address of BDR.
Priority
: The OSPF priority. It helps determine the DR and BDR on the network to which this interface is
connected.
Cost
: The cost of the interface.
Hello
: Hello timer. A time interval that a router sends an OSPF hello packet.
Dead
: Dead timer. Dead timer is a time interval to wait before declaring a neighbor dead. The unit of time is the
second.
Wait
: This interval is used in Wait Timer. Wait timer is a single shot timer that causes the interface to exit
waiting and select a DR on the network. Wait Time interval is the same as Dead time interval.
Retransmit
: Retransmit timer. A time interval to wait before retransmitting a database description packet when
it has not been acknowledged.
Hello Timer
: Hello due timer. An OSPF hello packet will be sent on this interface after this due time.
Neighbor
: Neighbor count. This is the number of OSPF neighbors discovered on this interface.
Adj Count
: Adjacent neighbor count. This is the number of routers running OSPF that are fully adjacent with this
router. When OSPF neighbor adjacency is not in the full state then it is in one of the other states: there’s no
