Cisco ROUTE 1.0: Implementing an OSPF-Based Solution

Course details

Configuring Open Shortest Path First (OSPF) in today's networks is an important skill to have as a network administrator. You will need to understand the primary configuration commands for single-area and multiarea OSPF designs, and the commands used to verify configurations. OSPF presents some design limitations, but offers up solutions for each. Scalability, improved CPU and memory utilization, and the ability to mix small routers with large routers are all benefits of using proper route summarization techniques which is a key feature of OSPF. An OSPF network can scale to very large sizes, in part because of route summarization. Default routes can reduce routing table size, and also reduce memory and CPU utilization. The use of special-case area types to inject default routes reduce the amount of flooding, the link-state database (LSDB) size, and the routing table size in routers within the area. Network designers should always consider using stub area techniques when building networks. Stub area techniques improve performance in OSPF networks and allow the network to scale to significantly larger sizes. Preventing your router from receiving fraudulent route updates by configuring neighboring router authentication is important. You can configure OSPF neighbor authentication in such a way that routers can participate in routing based on predefined passwords. This course discusses the primary configuration commands for a single-area and multiarea OSPF design and how to configure the router for OSPF. It covers OSPF design limitation solutions such as virtual links, passive interface command, and changing the cost metric. The different types of route summarization and the configuration commands for each type, and the benefits of default routes and how to configure them will also be discussed. Finally, OSPF area types, OSPF authentication types, and how to configure and verify them will also be explained.
