Display Message
If you do not specify an IP address, a table with the following columns displays for all neighbors. If you specify a
interface, only the information for that interface displays:
Fields
Definition
Router ID
The 4-digit dotted-decimal number of the neighbor router.
Priority
The OSPF priority for the specified interface. The priority of an interface is a
priority integer from 0 to 255. A value of '0' indicates that the router is not eligible
to become the designated router on this network.
IP Address
The IP address of the neighbor.
Interface
The interface of the local router in slot/port format.
State
The state of the neighboring routers. Possible values are:
• Down - initial state of the neighbor conversation - no recent
information has been received from the neighbor.
• Attempt - no recent information has been received from the neighbor
but a more concerted effort should be made to contact the neighbor.
• Init - an Hello packet has recently been seen from the neighbor, but
bidirectional communication has not yet been established.
• 2 way - communication between the two routers is bidirectional.
• Exchange start - the first step in creating an adjacency between the
two neighboring routers, the goal is to decide which router is the
master and to decide upon the initial DD sequence number.
• Exchange - the router is describing its entire link state database by
sending Database Description packets to the neighbor.
• Loading - Link State Request packets are sent to the neighbor asking
for the more recent LSAs that have been discovered (but not yet
received) in the Exchange state.
• Full - the neighboring routers are fully adjacent and they will now
appear in router-LSAs and network-LSAs.
