ICND v2.0—5-3 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 © 2002, Cisco Systems, Inc. All rights reserved. ICND v2.0—5-4 • Maximum is 6 paths (default = 4) • Hop-count metric selects the path • Routes update every 30 seconds RIP Overview © 2002, Cisco Systems, Inc.
