Customizing OSPFv2
Configuring OSPFv2 Interface Parameters
You can change some interface-specific OSPFv2 parameters, if necessary. You are not required to change
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. If you
configure any of these parameters, be sure that the configurations for all routers on your network have
compatible values.
To configure OSPFv2 interface parameters, perform the following steps:
Detailed Steps
Command
Step 1
router ospf process_id
Example:
hostname(config)# router ospf 2
Step 2
network ip_address mask area area_id
Example:
hostname(config)# router ospf 2
hostname(config-rtr)# network 10.0.0.0
255.0.0.0 area 0
Step 3
interface interface_name
Example:
hostname(config)# interface my_interface
Step 4
Do one of the following to configure optional OSPF interface parameters:
ospf authentication [message-digest | null]
Example:
hostname(config-interface)# ospf
authentication message-digest
ospf authentication-key key
Example:
hostname(config-interface)# ospf
authentication-key cisco

Purpose
Creates an OSPF routing process and enters router configuration
mode for the OSPF process that you want to redistribute.
The process_id argument is an internally used identifier for this
routing process and can be any positive integer. This ID does not
have to match the ID on any other device; it is for internal use
only. You can use a maximum of two processes.
Defines the IP addresses on which OSPF runs and the area ID for
that interface.
Allows you to enter interface configuration mode.
Specifies the authentication type for an interface.
Allows you to assign a password to be used by neighboring OSPF
routers on a network segment that is using the OSPF simple
password authentication.
The key argument 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 ASA 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.
