Configuring OSPF
The ip-mask parameter specifies the portions of the IP address that a route must contain to be
summarized in the summary route. In the example above, all networks that begin with 193.45 are
summarized into a single route.
Assigning interfaces to an area
Once you define OSPF areas, you can assign interfaces to the areas. All router ports must be
assigned to one of the defined areas on an OSPF router. When a port is assigned to an area, all
corresponding subnets on that port are automatically included in the assignment.
To assign interface 1/1/8 to area 192.168.0.0 and then save the changes, enter the following
commands.
Brocade(config-ospf-router)#interface e 1/1/8
Brocade(config-if-e10000-1/1/8)#ip ospf area 192.168.0.0
Brocade(config-if-e10000-1/1/8)#write memory
Modifying interface defaults
OSPF has interface parameters that you can configure. For simplicity, each of these parameters
has a default value. No change to these default values is required except as needed for specific
network configurations.
Port default values can be modified using the following commands at the interface configuration
level of the CLI:
•
ip ospf area ip-addr
•
ip ospf auth-change-wait-time secs
•
ip ospf authentication-key [0 | 1] string
•
ip ospf cost num
•
ip ospf dead-interval value
•
ip ospf hello-interval value
•
ip ospf md5-authentication key-activation-wait-time num | key-id num [0 | 1] key string
•
ip ospf passive
•
ip ospf priority value
•
ip ospf retransmit-interval value
•
ip ospf transmit-delay value
For a complete description of these parameters, see the summary of OSPF port parameters in the
next section.
OSPF interface parameters
The following parameters apply to OSPF interfaces.
Area: Assigns an interface to a specific area. You can assign either an IP address or number to
represent an OSPF Area ID. If you assign a number, it can be any value from 0 through
2,147,483,647.
