Chapter 21 Configuring OSPF
Customizing OSPF
To define a static OSPF neighbor, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Static
Neighbor.
Step 2 Click the Area/Networks tab.
The Add/Edit OSPF Neighbor Entry dialog box appears. This dialog box lets you define a new static
neighbor or change information for an existing static neighbor. You must define a static neighbor for
each point-to-point, non-broadcast interface. Note the following restrictions:
• You cannot define the same static neighbor for two different OSPF processes.
• You need to define a static route for each static neighbor.
Step 3 From the OSPF Process drop-down list, choose the OSPF process associated with the static neighbor. If
you are editing an existing static neighbor, you cannot change this value.
Step 4 In the Neighbor field, enter the IP address of the static neighbor.
Step 5 In the Interface field, choose the interface associated with the static neighbor. If you are editing an
existing static neighbor, you cannot change this value.
Step 6 Click OK.
Configuring Route Calculation Timers
You can configure the delay time between when OSPF receives a topology change and when it starts an
SPF calculation. You also can configure the hold time between two consecutive SPF calculations.
To configure route calculation timers, perform the following steps:
Step 1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Setup.
Step 2 Click the Process Instances tab.
Step 3 Choose the OSPF process that you want to edit, then click Advanced.
The Edit OSPF Process Advanced Properties dialog box appears.
Step 4 In the Timers area, enter the following values:
The Timers area allows you to modify the settings that are used to configure LSA pacing and SPF
calculation timers.
• SPF Delay Time—Specifies the time between when OSPF receives a topology change and when the
SPF calculation starts. Valid values range from 0 to 65535. The default value is 5.
• SPF Hold Time—Specifies the hold time between consecutive SPF calculations.Valid values range
from 1 to 65534. The default value is 10.
• LSA Group Pacing—Specifies the interval at which LSAs are collected into a group and refreshed,
check summed, or aged. Valid values range from 10 to 1800. The default value is 240.
Step 5 Click OK.
