Configuring OSPF
25
The <num> | <ip-addr> parameter specifies the area number, which can be in IP address format.
The range <ip-addr> parameter specifies the IP address portion of the range. The software
compares the address with the significant bits in the mask. All network addresses that match this
comparison are summarized in a single route advertised by the router.
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 1/8 of Router A to area 192.5.0.0 and then save the changes, enter the
following commands.
RouterA(config-ospf-router)# interface e 1/8
RouterA(config-if-e10000-1/8)# ip ospf area 192.5.0.0
RouterA(config-if-e10000-1/8)# write memory
Modify 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 CLI 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.
