Objectives
Upon completing this lesson, you will be
able to:
•
Describe the features and operation of RIP
•
Use Cisco IOS commands to configure dynamic
routing using RIP, given a functioning router
•
Use show and debug commands to identify
anomalies in dynamic routing operation using
RIP, given an operational router

•
Maximum is 6 paths (default = 4)
•
Hop-count metric selects the path
•
Routes update every 30 seconds

Specify networks or
interfaces.
IP Routing
Configuration Tasks
© 2002, Cisco Systems, Inc. All rights reserved. ICND v2.0—5-6
•
Defines an IP routing protocol
Router(config)#router protocol [keyword]
•
Mandatory configuration command for each
IP routing process
•
Identifies the physically connected network that
routing updates are forwarded to
Router(config-router)#network network-number
Dynamic Routing Configuration
© 2002, Cisco Systems, Inc. All rights reserved. ICND v2.0—5-7
•
Starts the RIP routing process
Router(config)#router rip
Router(config-router)#network network-number
•
Selects participating attached networks
•
Requires a major classful network number
