Comprehensive Guide to Router Configuration and Connectivity

This guide covers essential concepts for configuring and connecting various routers. It includes foundational topics such as connecting console interfaces, LAN and WAN interfaces, and establishing console sessions using Hyperterminal. The chapter elaborates on command modes, router interface configurations, setting up passwords, and using show commands. Understanding routable protocols like IP and routing protocols such as RIP is critical. Engage in practical labs to refine skills in interface configuration, including message-of-the-day settings, host table management, and effective troubleshooting.

Presentation Transcript

  1. Chapter 1 Wans and Routers • 1.2.5 Connecting Console Interface • 1.2.6 Connecting Router LAN Interfaces • 1.2.7 Connecting WAN Interfaces These labs have already been completed earlier

  2. Chapter 2 Introduction to Routers • 2.2.1 Router Configuration Using Setup • 2.2.4 Establishing a Console Session with Hyperterminal • 2.2.9 Command Line Fundamentals

  3. Chapter 3 Configuring a Router • 3.1.2 Command Modes and Router Interfaces • 3.1.3 Configuring Router Passwords • 3.1.4 Using Router Show Commands • 3.1.5 Configuring a Serial Interface • 3.1.7 Configuring an Ethernet Interface • 3.2.3 Configuring Interface Descriptions • 3.2.5 Configuring Message-of-the-Day (MOTD) • 3.2.7 Configuring Host Tables • 3.2.4 Copying, Editing and Pasting Configurations.

  4. The six main modes available with most routers: • User EXEC Mode • Privileged EXEC Mode (also known as Enable Mode) • Global Configuration Mode • Router Configuration Mode • Interface Configuration Mode • Sub-interface Configuration Mode

  5. Router modes • user EXEC mode -- This is a look-only mode in which the user can view some information about the router, but can change nothing. • privileged EXEC mode -- This mode supports the debugging and testing commands, detailed examination of the router, manipulation of configuration files, and access to configuration modes. • setup mode -- This mode presents an interactive prompted dialog at the console that helps the new user create a first-time basic configuration.

  6. Router modes • global configuration mode -- This mode implements powerful one-line commands that perform simple configuration tasks. • other configuration modes -- These modes provide more detailed multiple-line configurations. • RXBOOT mode -- This is the maintenance mode that you can use, among other things, to recover from lost passwords.

  7. Routable vs Routing Protocols • Routable Protocols transmit user data, ie traffic of the network. The most commonly used is IP, others include IPX/SPX and AppleTalk • Routing protocol transmit information regarding the structure of the network. Examples include RIP.

  8. Challenge Lab • Work in pairs • Each individual selects a router • Attach PC to it via Hub • Console into Router • Attach router to other groups router via either serial 0 or 1 cable shown • Use two class C addresses • Use IP address of 192.168.x.0

  9. Use 1st IP address of Subnet for router fast ethernet interface • Use 1st IP address of subnet for routers S0/0 interface • Use 2nd IP address of subnet for routers S0/1 interface

  10. Configure the Following • Router Passwords • Serial Interface and Ethernet Interface • Interface Descriptions • Message-of-the-Day (MOTD) • Configuring Host Tables • Copying, Editing and Pasting Configurations. • Using Router Show Commands

  11. Configure the Following • Configure RIP as the routing protocol • Establish connectivity between the router’s networks
