Routing Overview
Objectives
pleting this lesson, you will be able to:
Explain the differences between static routing and dynamic routing
Identify the classes of routing protocols
Use Cisco mands to configure static routes and default route forwarding, given a functioning router
Use mands to identify anomalies in static routing operation, given an operational router
Describe the operation of “router on a stick”
Configure router on a stick for inter-VLAN routing using ISL and trunking, given an operational switch and router
To route, a router needs to do the following:
Know the destination address
Identify the sources it can learn from
Discover possible routes
Select the best route
Maintain and verify routing information
What Is Routing?
Routers must learn destinations that are not directly connected.
What Is Routing? (Cont.)
Static Route
Uses a route that work administrator enters into the router manually
Dynamic Route
Uses a route that work routing protocol adjusts automatically for topology or traffic changes
Identifying Static and Dynamic Routes
Static Routes
Configure unidirectional static routes to and from a work to munications to occur.
Defines a path to an IP work or or host
Router(config)#ip work [mask] {address | interface}[distance] [permanent]
Static Route Configuration
