Configuring OSPF Interface Parameters

You can alter some interface-specific OSPF parameters as necessary. You are not required to alter any
of these parameters, but the following interface parameters must be consistent across all routers in an
attached network: ospf hello-interval, ospf dead-interval, and ospf authentication-key. Be sure that if
you configure any of these parameters, the configurations for all routers on your network have
compatible values.
To configure OSPF interface parameters, perform the following steps:
To enter the interface configuration mode, enter the following command:
Step 1
hostname(config)# interface if_name
Enter any of the following commands:
Step 2

To specify the authentication type for an interface, enter the following command:
hostname(config-interface)# ospf authentication [message-digest | null]
To assign a password to be used by neighboring OSPF routers on a network segment that is using
the OSPF simple password authentication, enter the following command:
hostname(config-interface)# ospf authentication-key key
The key can be any continuous string of characters up to 8 bytes in length.
The password created by this command is used as a key that is inserted directly into the OSPF header
when the FWSM software originates routing protocol packets. A separate password can be assigned
to each network on a per-interface basis. All neighboring routers on the same network must have the
same password to be able to exchange OSPF information.
To explicitly specify the cost of sending a packet on an OSPF interface, enter the following
command:
hostname(config-interface)# ospf cost cost
The cost is an integer from 1 to 65535.
To set the number of seconds that a device must wait before it declares a neighbor OSPF router down
because it has not received a hello packet, enter the following command:
hostname(config-interface)# ospf dead-interval seconds
The value must be the same for all nodes on the network.
To specify the length of time between the hello packets that the FWSM sends on an OSPF interface,
enter the following command:
hostname(config-interface)# ospf hello-interval seconds
The value must be the same for all nodes on the network.
To enable OSPF MD5 authentication, enter the following command:
hostname(config-interface)# ospf message-digest-key key_id md5 key
Set the following values:
key_id—An identifier in the range from 1 to 255.
