Chapter 5: Multiarea OSPF
Labs:
5.8.1 In this lab, you configure multiarea OSPF operation, interarea summarization, external route summarization, and default routing.
5.8.2 In this lab, you configure an OSPF stub area and a totally stubby area.
5.8.3 In this lab, you configure an OSPF NSSA in order to import external routing information while retaining the benefits of a stub area.
5.8.4 In this lab, you configure an OSPF virtual link so that a disconnected area can reach the backbone, as required by OSPF.
5.9.1 In this lab, you create a multiarea OSPF autonomous system that includes a totally stubby area and a persistent default route toward the ISP.
Interactive Labs:
5.3.1 The purpose of this activity is to configure an Area Border Router in a multiarea OSPF environment. SanJose1 and the Singapore routers have already been configured for OSPF routing. Your task is to configure SanJose3 to enable Inter-Area routing.
5.5.3 The purpose of this activity is to configure an OSPF virtual link so that the disconnected Area 3 can reach the backbone Area 0, as required by OSPF. Although Multi-Area OSPF has already been configured, you will configure a virtual link through Area 51 connecting Area 3 to the backbone Area 0.
