Starting and Configuring the Router

Upon completion of the upgrade the router reboots with the running Boot ROM upgraded.

4.2 Router Configuration Basics

4.2.1 Basic Configuration Procedures

The following are the general procedures for configuring the router:

Step 1: Before working on the router, fully comprehend network requirements, such as networking purpose, position of the router on the network, subnetting, type of the WAN and transmission medium, security policy and reliability.

Step 2: Based on the requirements, draw a clear and complete networking diagram.

Step 3: Configure the WAN interface on the router.

First, configure the physical operating parameters (such as synchronous/asynchronous serial interface, baud rate and synchronization clock) of the interface according to the transmission medium of the WAN. For the dial-up interface, you also need to configure DCC parameters.

Then, configure the link layer protocol and the related operating parameters according to the type of the WAN.

Step 4: Assign an IP address or IPX network number to each interface on the router according to subnetting.

Step 5: Configure routing. When enabling a dynamic routing protocol, you also need to configure the related operating parameters.

Step 6: Configure the security settings as needed.

Step 7: Configure the reliability settings as needed.

For more information on the protocols and functions provided by the router, refer to V2.41 Configuration Guide.

4.2.2 Command Line Interface

I. Characteristics of the command line interface

The command line interface (CLI) available with the 3Com Router 6000 provides commands for configuring and managing the router. It supports:

zConfiguring the router locally through the console port.

zTelneting to the router to configure it locally or remotely; telneting from the router to other routers to manage them.

zGetting online help whenever you want by entering a question mark (?).

zTesting reachability of networks quickly with tools, such as tracert and ping.

zRich debugging information for network diagnosis.
