CP6923 Routing Commands
Page 4 - 57 CP6923 CLI Reference Manual
If you specify an IP address for the neighbor router, the following fields display:
Example: The following shows example CLI display output for the command.
(alpha1) #show ip ospf neighbor 170.1.1.50
Interface.....................................0/17
Neighbor IP Address...........................170.1.1.50
Interface Index...............................17
Area Id.......................................0.0.0.2
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.
Dead Time The amount of time, in seconds, to wait before the router assumes the neighbor is
unreachable.
Term Definition
Interface Valid slot and port number separated by forward slashes.
Neighbor IP
Address
The IP address of the neighbor router.
Interface Index The interface ID of the neighbor router.
Area ID The area ID of the OSPF area associated with the interface.
Options An integer value that indicates the optional OSPF capabilities supported by the neighbor. The
neighbor's optional OSPF capabilities are also listed in its Hello packets. This enables
received Hello Packets to be rejected (i.e., neighbor relationships will not even start to form)
if there is a mismatch in certain crucial OSPF capabilities.
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.
Dead Timer Due The amount of time, in seconds, to wait before the router assumes the neighbor is
unreachable.
Up Time Neighbor uptime; how long since the adjacency last reached the Full state.
State The state of the neighboring routers.
Events The number of times this neighbor relationship has changed state, or an error has occurred.
Retransmission
Queue Length
An integer representing the current length of the retransmission queue of the specified
neighbor router Id of the specified interface.
