Configuring OSPF
As per the Figure 6-9 arrangement diagram, OSPF can be configured on the central and alfresco interfaces.
Note
RIP and OSPF on the aforementioned firewall apparatus was not accurate in adaptation 7.0 or prior. However,
multiprotocol is now absolutely accurate from v7.2 and later, as illustrated in Figure 6-9.
Example 6-8 shows how to accredit two abstracted OSPF processes with alternate two-way redistribution to allow
devices on both abandon of the Security Apparatus to apprentice networks from anniversary other.
Example 6-8. Configuring Two OSPF Processes (for Central and Alfresco Interfaces) with Two-Way
Redistribution
hostname(config)# router ospf 1
hostname(config-router)# arrangement 10.1.1.0 255.255.255.0 breadth 0
hostname(config-router)# redistribute ospf 2 metric 1 subnets
hostname(config)# router ospf 2
hostname(config-router)# arrangement 10.1.2.0 255.255.255.0 breadth 0
hostname(config-router)# redistribute ospf 1 metric 1 subnets
Several interface-specific OSPF ambit can be configured as accounted necessary, including OSPF Hello or
dead intervals, OSPF priority, and affidavit keys. Example 6-9 shows some of the OSPF ambit that
can be enabled beneath the interface.
Example 6-9. Configuring OSPF Interface-Specific Parameters
hostname(config-router)# interface inside
hostname(config-interface)# ospf amount 10
hostname(config-interface)# ospf retransmit-interval 10
hostname(config-interface)# ospf transmit-delay 5
hostname(config-interface)# ospf antecedence 255
hostname(config-interface)# ospf hello-interval 5
hostname(config-interface)# ospf dead-interval 20
hostname(config-interface)# ospf authentication-key cisco
hostname(config-interface)# ospf message-digest-key 1 md5 cisco
hostname(config-interface)# ospf affidavit message-digest
Several OSPF ambit can be configured beneath the breadth that will affect the absolute OSPF domain/area.
Examples accommodate authentication, avenue summarization, avenue filtering, and defining butt areas. Example 6-10
shows some of the OSPF ambit that can be enabled areawide.
Example 6-10. Examples of Areawide OSPF Parameters
hostname(config)# router ospf 1
hostname(config-router)# breadth 1 default-cost 10
hostname(config-router)# breadth 1 stub
hostname(config-router)# breadth 1 butt no-summary
hostname(config-router)# breadth 0 ambit 10.1.1.0 255.255.255.0
hostname(config-router)# breadth 0 filter-list prefix mylist in
