Cisco Systems OL-4580-01 Assigning an OSPF Area to the Interface, Enabling OSPF on the Interface

Chapter 3 Configuring Open Shortest Path First (OSPF)

Configuring OSPF on a CSS IP Interface

Assigning an OSPF Area to the Interface

After you configure the IP interface as an OSPF interface, assign it to the area that you globally configured to the CSS. The default area is the backbone area with the ID of 0.0.0.0. If the area is other than the backbone, use the ospf area command to assign the interface to an OSPF area. For example, if the area is 0.0.0.1, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf area 0.0.0.1

To reset the interface to the default backbone area, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# no ospf area

Enabling OSPF on the Interface

If you need to configure the interface attributes as described in the “Configuring the Interface Attributes” section, do not enable OSPF on the IP interface until you finish configuring the attributes.

By default, OSPF is disabled on an IP interface. Use the ospf enable command to enable OSPF on the IP interface. For example:

(config-circuit-ip[VLAN6-3.1.2.2])# ospf enable

To disable OSPF on the interface, enter:

(config-circuit-ip[VLAN6-3.1.2.2])# no ospf enable

Configuring the Interface Attributes

The OSPF interface attributes are set to a series of default values. You can elect to use these values for the CSS IP interface or configure your own settings. This section includes the following topics:

•Setting the Cost

•Setting the Dead Router Interval

•Setting the Hello Packet Interval

•Setting the Password

•Setting the Poll Interval

•Setting the Priority of the CSS
