Chapter 8 Configuring IP Routing and DHCP Services

Configuring OSPF

Enabling OSPF

To enable OSPF, you need to create an OSPF routing process, specify the range of IP addresses

associated with the routing process, then assign area IDs associated with that range of IP addresses.

Note You cannot enable OSPF if RIP is enabled.

To enable OSPF, perform the following steps:

Step 1 To create an OSPF routing process, enter the following command:

hostname(config)# router ospf

process_id

This command enters the router configuration mode for this OSPF process.

The process_id is an internally used identifier for this routing process. It can be any positive integer. This

ID does not have to match the ID on any other device; it is for internal use only. You can use a maximum

of two processes.

Step 2 To define the IP addresses on which OSPF runs and to define the area ID for that interface, enter the

following command:

hostname(config-router)# network

ip_address mask

area

area_id

The following example shows how to enable OSPF:

hostname(config)# router ospf 2

hostname(config-router)# network 10.0.0.0 255.0.0.0 area 0

Redistributing Routes Between OSPF Processes

The security appliance can control the redistribution of routes between OSPF routing processes. The

security appliance matches and changes routes according to settings in the redistribute command or by

using a route map. See also the “Generating a Default Route” section on page 8-13 for another use for

route maps.

Note The security appliance cannot redistribute routes between routing protocols. However, the security

appliance can redistribute static and connected routes.

This section includes the following topics:

• Adding a Route Map, page 8-6

• Redistributing Static, Connected, or OSPF Routes to an OSPF Process, page 8-7
