Chapter 24 Configuring OSPF
Configuration Example for OSPF
Step 3
(Optional) To configure OSPF interface parameters, enter the following commands:
hostname(config)# router ospf 2
hostname(config-router)# network 10.0.0.0 255.0.0.0 area 0
hostname(config-router)# interface inside
hostname(config-interface)# ospf cost 20
hostname(config-interface)# ospf retransmit-interval 15
hostname(config-interface)# ospf transmit-delay 10
hostname(config-interface)# ospf priority 20
hostname(config-interface)# ospf hello-interval 10
hostname(config-interface)# ospf dead-interval 40
hostname(config-interface)# ospf authentication-key cisco
hostname(config-interface)# ospf message-digest-key 1 md5 cisco
hostname(config-interface)# ospf authentication message-digest
Step 4
(Optional) To configure OSPF area parameters, enter the following commands:
hostname(config)# router ospf 2
hostname(config-router)# area 0 authentication
hostname(config-router)# area 0 authentication message-digest
hostname(config-router)# area 17 stub
hostname(config-router)# area 17 default-cost 20
Step 5
(Optional) To configure the route calculation timers and show the log neighbor up and down messages,
enter the following commands:
hostname(config-router)# timers spf 10 120
hostname(config-router)# log-adj-changes [detail]
Step 6
To restart the OSPF process, enter the following commands:
hostname(config)# clear ospf pid {process | redistribution | counters
[neighbor [neighbor-interface] [neighbor-id]]}
Step 7
(Optional) To show current OSPF configuration settings, enter the show ospf command.
The following is sample output from the show ospf command:
hostname(config)# show ospf
