This example shows a number of different paths that a message can take when leaving R1 and destined for R6. When configuring static routing, typically the engineer has a single path in mind to reach the destination.
So, to configure a route from R1 to R6 using the path through R2 and R4, a static route would need to exist on R1, R2, and R4 for the forward trip (R1 To provide reachability to every destination that potentially exists in the network, the engineer would need to calculate the best paths for each destination initially, and then individually configure each route along each best path.
is typically used on very small networks, where the number of routes to be configured is just as small.In this two-part series, Sean Wilkins, co-author of CCNA Routing and Switching 200-120 Network Simulator, discusses current network routing protocols and methods for implementing them.This article covers the types of static versus dynamic routing protocols and the differences between them.After selecting the dynamic routing method, the engineer must make some additional decisions involving the types of dynamic routing protocols.At the highest level are two main categories of dynamic routing protocol: in this case is a specific organization or service provider network.) IGPs handle the routing inside these network domains; these protocols are the most common, as each company with a network handles its own network domain.
is built to deal with network changes automatically as the topology changes within the network, and are typically used on all other network types not previously mentioned.
