In this article we will discuss Fine-tuning Routing Protocols, will make brief discussion on Fine-tuning Routing Protocols, In last article we discuss about Expanding the Access Layer.
Advanced routing protocols, such as OSPF and EIGRP are used in large networks.
Link-state routing protocols such as Open Shortest Path First (OSPF), works well for larger hierarchical networks where fast convergence is important. OSPF routers establish and maintain neighbor adjacency or adjacencies, with other connected OSPF routers.
When routers initiate an adjacency with neighbors, an exchange of link-state updates begins. Routers reach a FULL state of adjacency when they have synchronized views on their link-state database. With OSPF, link state updates are sent when network changes occur.
Additionally, OSPF supports a two-layer hierarchical design, referred to as multiarea OSPF. All multiarea OSPF networks must have an Area 0, also called the backbone area. Non-backbone areas must be directly connected to area 0. Chapter 9 titled “Multiarea OSPF” introduces the benefits, operation, and configuration of Multiarea OSPF. Chapter 10, “OSPF Tuning and Troubleshooting”, will cover the more advanced features of OSPF.
Another popular routing protocol for larger networks is Enhanced Interior Gateway Routing Protocol (EIGRP). Cisco developed EIGRP as a proprietary distance vector routing protocol with enhanced capabilities. Although configuring EIGRP is relatively simple, the underlying features and options of EIGRP are extensive and robust. For example, EIGRP uses multiple tables to manage the routing process. EIGRP contains many features that are not found in any other routing protocols. It is an excellent choice for large, multi-protocol networks that employ primarily Cisco devices.
Chapter 6 titled “EIGRP” introduces the operation and configuration of the EIGRP routing protocol, while chapter 7 titled “EIGRP Tuning and Troubleshooting” covers some of the more advanced configuration options of EIGRP.
