Cisco IOS XR for OSPF Version 2 Configuration: Example
The following example shows how an OSPF interface is configured for an area in
Cisco IOS XR software.
In Cisco IOS XR software, area 0 must be explicitly configured with the area command and all
interfaces that are in the range from 10.1.2.0 to 10.1.2.255 are bound to area 0. Interfaces are configured
with the interface command (while the router is in area configuration mode) and the area keyword is
not included in the interface statement.

Step 6
show {ospf | ospfv3}[
process-name
] [
area-id
]
neighbor [
interface-type interface-instance
]
[
neighbor-id
] [detail]
Example:
RP/0/RP0/CPU0:router# show ospf 100 neighbor
(Optional) Displays OSPF neighbor information on an
individual interface basis.
Step 7
clear {ospf | ospfv3}[
process-name
] process
Example:
RP/0/RP0/CPU0:router# clear ospf 100 process
(Optional) Resets an OSPF router process without stopping
and restarting it.
Step 8
clear {ospf | ospfv3}[
process-name
] statistics
[neighbor [
interface-type interface-instance
]
[
ip-address
]]
Example:
RP/0/RP0/CPU0:router# clear ospf 100 statistics
(Optional) Clears the OSPF statistics of neighbor state
transitions.
