Neighbor Events The number of times this neighbor relationship has changed state,
or an error has occurred.
External LSA Count The number of external (LS type 5) link-state advertisements
in the link-state database.
3.7.49 show ip ospf neighbor
This command displays information about OSPF neighbors. If you do not specify a
neighbor IP address, the output displays summary information in a table. If you specify
an interface or tunnel, only the information for that interface or tunnel displays. The
is the IP address of the neighbor, and when you specify this, detailed
information about the neighbor displays. The information below only displays if OSPF
is enabled and the interface has a neighbor.
Format show ip ospf neighbor [interface <slot/port>] [address>]
Modes Privileged EXEC
User EXEC
If you do not specify an IP address, a table with the following columns displays for all
neighbors or the neighbor associated with the interface that you specify:
Router ID Shows the 4-digit dotted-decimal number of the neighbor router.
Priority Displays 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 Shows the IP address of the neighbor.
Interface Shows the interface of the local router in slot/port format.
State Shows the state of the neighboring routers. Possible values are:
Down- initial state of the neighbor conversation - no recent informa-
tion 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.
