Configuring OSPF

You also can change the amount of memory allocated to various types of LSA entries. However,

these changes require a system reset or reboot.

Configuring OSPF

Follow the steps given below to begin using OSPF on the router.

1. Enable OSPF on the router.

2. Assign the areas to which the router will be attached.

3. Assign individual interfaces to the OSPF areas.

4. Define redistribution filters, if desired.

5. Enable redistribution, if you defined redistribution filters.

6. Modify default global and port parameters as required.

7. Modify OSPF standard compliance, if desired.

NOTE

OSPF is automatically enabled without a system reset.

Configuration rules

• If a router is to operate as an ASBR, you must enable the ASBR capability at the system level.

• Redistribution must be enabled on routers configured to operate as ASBRs.

• 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.

OSPF parameters

You can modify or set the following global and interface OSPF parameters.

Global parameters:

• Modify OSPF standard compliance setting.

• Assign an area.

• Define an area range.

• Define the area virtual link.

• Set global default metric for OSPF.

• Change the reference bandwidth for the default cost of OSPF interfaces.

• Disable or re-enable load sharing.

• Enable or disable default-information-originate.

• Modify Shortest Path First (SPF) timers

• Define external route summarization

• Define redistribution metric type.
