Chapter27 Configuring OSPF
Customizing OSPF
Step6 Enter the network mask in the Network Mask field for the IP address or host to be added to the area. If
adding a host, choose the 255.255.255.255 mask.
Step7 In the Authentication area, click the None radio button to disable OSPF area authentication.
Step8 Enter a value in the Default Cost field to specify a default cost for the OSPF area.
Valid values range from 0 to 65535. The default value is 1.
Step9 Click OK.
Defining Static OSPF Neighbors
You need to define static OSPF neighbors to advertise OSPF routes over a point-to-point, non-broadcast
network. This feature lets you broadcast OSPF advertisements across an existing VPN connection
without having to encapsulate the advertisements in a GRE tunnel.
Before you begin, you must create a static route to the OSPF neighbor. See Chapter25, “Configuring
Static and Default Routes,” for more information about creating static routes.
To define a static OSPF neighbor, perform the following steps:
Step1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Static
Neighbor.
Step2 Click Add or Edit.
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, nonbroadcast 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.
Step3 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.
Step4 In the Neighbor field, enter the IP address of the static neighbor.
Step5 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.
Step6 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:
Step1 In the main ASDM window, choose Configuration > Device Setup > Routing > OSPF > Setup.
Step2 Click the Process Instances tab.
