Chapter 11 Routing Protocols Figure 108 OSPF: Virtual Link In this example, area 100 does not have a direct connection to the backbone. As a result, you should set up a virtual link on both ABR in area 10. The virtual link becomes the connection between area 100 and the backbone. You cannot create a virtual link to a router in a different area. OSPF Configuration Follow these steps when you configure OSPF on the UAG. 1 Enable OSPF. 2 Set up the OSPF areas. 3 Configure the appropriate interfaces. See Section 8.3.1 on page 108. 4 Set up virtual links, as needed. 11.3.1 Configuring the OSPF Screen Use the first OSPF screen to specify the OSPF router the UAG uses in the OSPF AS and maintain the policies for redistribution. In addition, it provides a summary of OSPF areas, allows you to remove them, and opens the OSPF Add/Edit screen to add or edit them. Click Configuration > Network > Routing > OSPF to open the following screen. 170 UAG715 User's Guide
