Implementing OSPF
Command or Action
Example:
RP/0/RSP0/CPU0:router(config)# router ospf 1
or
RP/0/RSP0/CPU0:router(config)# router ospfv3
1
Step 3 router-id { router-id }
Example:
RP/0/RSP0/CPU0:router(config-ospf)# router-id
192.168.4.3
Step 4 area area-id
Example:
RP/0/RSP0/CPU0:router(config-ospf)# area 0
Step 5 network { broadcast | non-broadcast | {
point-to-multipoint [ non-broadcast ] |
point-to-point }}
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)# network
non-broadcast
Step 6 dead-interval seconds
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
dead-interval 40
Step 7 hello-interval seconds
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
hello-interval 10
Step 8 interface type interface-path-id
Example:
RP/0/RSP0/CPU0:router(config-ospf-ar)#
interface GigabitEthernet 0/2/0/0
Purpose
Note
Configures a router ID for the OSPF process.
Note
Enters area configuration mode and configures an area for the OSPF
process.
Configures the OSPF network type to a type other than the default
for a given medium.
(Optional) Sets the time to wait for a hello packet from a neighbor
before declaring the neighbor down.
(Optional) Specifies the interval between hello packets that OSPF
sends on the interface.
Note
Enters interface configuration mode and associates one or more
interfaces for the area configured in Step 4.

Configuring Neighbors for Nonbroadcast Networks
The process-name argument is any alphanumeric string
no longer than 40 characters.
We recommend using a stable IP address as the router
ID.
• The example configures a backbone area.
• The area-id argument can be entered in dotted-decimal or
IPv4 address notation, such as area 1000 or area 0.0.3.232.
However, you must choose one form or the other for an area.
We recommend using the IPv4 address notation.
• The example sets the network type to NBMA.
It is recommended to set the hello timer interval to the
default of 10 seconds. OSPF sessions may flap during
switchover if hello-interval timer configured is less then
default value.
• In this example, the interface inherits the nonbroadcast network
type and the hello and dead intervals from the areas because
the values are not set at the interface level.
