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:
Step 1
To enter the interface configuration mode, enter the following command:
hostname(config)#
interface
if_name
Step 2 Enter any of the following commands:
•
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.
