Overview/Description
Routing is the process by which information moves from one location to another. Routers gather and maintain routing information to enable the transmission and receipt of these data packets. Routing information takes the form of entries in a routing table, with one entry for each identified route. The router can use a routing protocol to create and maintain the routing table dynamically so that network changes can be accommodated whenever they occur. To effectively manage an IP network, you must understand the operation of dynamic routing protocols and the impact that they have on an IP network. This course describes the operation and limitations of distance vector and link-state routing protocols. Classless routing protocols scale better than classful routing protocols and the main reason why is that they support Variable-Length Subnet Masks (VLSMs) and route summarization. VLSMs were developed to allow multiple levels of subnetworked IP addresses within a single network. Protocols that have VLSM support include Routing Information Protocol version 2 (RIPv2), Open Shortest Path First (OSPF), and Enhanced Interior Gateway Routing Protocol (EIGRP). VLSM is a key technology on large routed networks and understanding the capabilities of VLSM is important when you are planning large networks. This course describes the capabilities of VLSMs.
