Configuring OSPF
The not-advertise parameter sets the address range status to DoNotAdvertise. Neither the
individual intra-area routes falling under range nor the ranged prefix is advertised as summary LSA.
The cost cost-value parameter specifies the cost-value to be used while generating type-3
summary LSA. If the cost value is configured, then configured cost is used while generating the
summary LSA. If the cost value is not configured, then computed range cost will be used. The
cost-value ranges from 1 - 16777215.
To disable this function, use the no form of this command.
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 10.5.0.0 and then save the changes, enter the following
commands.
RouterA(config)# interface e 1/8
RouterA(config-if-e10000-1/8)# ip ospf area 10.5.0.0
RouterA(config-if-e10000-1/8)# write memory
Setting all OSPFv2 interfaces to the passive state
You can set all the Open Shortest Path First Version 2 (OSPFv2) interfaces to the default passive
state using the default-passive-interface command. When you configure the interfaces as passive,
the interfaces drop all the OSPFv2 control packets.
To set all the OSPFv2 interfaces to passive, enter the following command.
Brocade# configure terminal
Brocade(config)# router ospf vrf A
Brocade(config-ospf-router-vrf-A)# default-passive-interface
Syntax: [no] default-passive-interface
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 string
• ip ospf cost num
• ip ospf database-filter all out
• ip ospf dead-interval value
• ip ospf hello-interval value
