To configure OSPF on a default routing instance or a VRF routing instance

Steps
 
1 

In the navigation tree Routing view, perform one of the following:

  1. For NEs that support multiple OSPF instances, expand Network→NE→Routing Instance→OSPFvN Instances, where N is the OSPF version number; for example, 2 or 3.

  2. For all other supported devices, expand Network→NE→Routing Instance→OSPFvN, where N is the OSPF version number; for example, 2 or 3.

2 

Perform one of the following:

  1. For NEs that support multiple OSPF instances, right-click on the appropriate OSPFvN Instances icon and choose Create OSPFvN Instance. The OSPF Site (Create) form opens. Go to Step 3 .

  2. For all other supported devices, right-click on the appropriate OSPFvN icon and choose Properties. The OSPF Site, Routing instance, OSPFvN instance (Edit) form opens. Go to Step 3 .

3 

Configure the required general parameters.

4 

Click on the Behavior tab and configure the required parameters.

Some parameters are configurable for OSPFv2 only.

Remote loop-free alternate uses segment routing by default. To configure segment routing, see To configure OSPF segment routing.

5 

Click on the Dijkstra tab and configure the required parameters:

For SPF:

  • SPF Max Wait (milliseconds)

  • Redistribute Delay (milliseconds)

  • Initial Wait (milliseconds)

  • Second Wait (milliseconds)

  • Incremental SPF Wait (milliseconds)

For LSA:

  • LSA Generate Max Wait (milliseconds)

  • LSA Arrival Wait (milliseconds)

  • Initial Wait (milliseconds)

  • Second Wait (milliseconds)

  • LSA Accumulate (milliseconds)

6 

Click on the Graceful Restart tab and configure the required parameters.

7 

Depending on the OSPF version, the Overload tab is configurable. Click on the Overload tab and configure the required parameters.

The Overload Interval (seconds) parameter is configurable when the Overload Enabled parameter is selected.

The Boot Overload Interval (seconds) parameter is configurable when the Boot Overload Enabled parameter is enabled.

8 

Click on the LFA tab and configure the required parameters.

Additional parameters are available when you select the Loop-free Alternate parameter.

9 

Configure participation in one or more flexible algorithms as needed:

  1. Click the Flexible Algorithms tab.

  2. Click Search to populate a list of flexible algorithms.

  3. Choose a flexible algorithm and click Properties, or click Create. The Flexible Algorithm (Create|Edit) form opens.

  4. Configure the Algorithm ID and Participate parameters.

  5. Select a local Flexible Algorithm Definition if needed.

  6. Click OK.

Repeat this step to add additional flexible algorithms as needed.

10 

If the OSPF version is OSPFv2, the OSPF Super-Backbone tab is configurable. Click on the OSPF Super-Backbone tab and configure the required parameters.

The following parameters apply only to VPRN instances of OSPF:

  • VPN Domain Type

  • VPN Domain ID (hex)

  • VPN Tag

  • Super-Backbone

11 

Click on the Import Policies and Export Policies tabs and configure the required parameters. Routing policies determine the routes that are advertised to peers, and are created as routing policy statements. See To configure a routing policy statement .

12 

Select up to five loop-free alternate policy statements on the LFA Policies tab.

13 

To configure segment routing, see To configure OSPF segment routing

14 

Click on the following tabs to add optional OSPF configuration items. Click Search to list previously configured items or click Create to create the item, if supported.

15 

Save your changes and close the form.
