You can configure the following optional parameters for OSPFv2 in interface configuration mode:
Command
ip ospf cost number
Example:
switch(config-if)# ip ospf cost 25
ip ospf dead-interval seconds
Example:
switch(config-if)# ip ospf dead-interval
50
ip ospf hello-interval seconds
Example:
switch(config-if)# ip ospf hello-interval
25
ip ospf mtu-ignore
Example:
switch(config-if)# ip ospf mtu-ignore
ip ospf passive-interface
Example:
switch(config-if)# ip ospf
passive-interface
ip ospf priority number
Example:
switch(config-if)# ip ospf priority 25
ip ospf shutdown
Example:
switch(config-if)# ip ospf shutdown
This example shows how to add a network area 0.0.0.10 in OSPFv2 instance 201:
switch# configure terminal
switch(config)# interface ethernet 1/2
switch(config-if)# no switchport
switch(config-if)# ip address 192.0.2.1/16
switch(config-if)# ip router ospf 201 area 0.0.0.10
switch(config-if)# copy running-config startup-config
Use the show ip ospf interface command to verify the interface configuration. Use the show ip ospf
neighbor command to see the neighbors for this interface.

Configuring Authentication for an Area

You can configure authentication for all networks in an area or for individual interfaces in the area.
Interface authentication configuration overrides area authentication.

Purpose
Configures the OSPFv2 cost metric for this
interface. The default is to calculate cost metric,
based on reference bandwidth and interface
bandwidth. The range is from 1 to 65535.
Configures the OSPFv2 dead interval, in seconds.
The range is from 1 to 65535. The default is four
times the hello interval, in seconds.
Configures the OSPFv2 hello interval, in seconds.
The range is from 1 to 65535. The default is 10
seconds.
Configures OSPFv2 to ignore any IP MTU
mismatch with a neighbor. The default is to not
establish adjacency if the neighbor MTU does not
match the local interface MTU.
Suppresses routing updates on the interface.
Configures the OSPFv2 priority, used to determine
the DR for an area. The range is from 0 to 255. The
default is 1. See the "Designated Routers" section
on page 3-3.
Shuts down the OSPFv2 instance on this interface.
