Configuring OSPF Interface Parameters
Single context mode only
Routed firewall mode only
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: ip ospf hello-interval, ip ospf dead-interval, and ip 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, follow these steps:
Step 1 To enter the interface configuration mode, enter the following command:
FWSM(config)# interface interface_name
Step 2 Enter any of the following commands:
• To specify the authentication type for an interface, enter the following command:
FWSM(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:
FWSM(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:
FWSM(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:
FWSM(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:
FWSM(config-interface)# ospf hello-interval seconds
The value must be the same for all nodes on the network.
