Background Preparation Any router that meets the interface requirements may be used. Possible routers include 800 1600 1700 2500 2600 routers or a combination. Refer to the chart at the end of the lab to correctly identify the interface identifiers to be used based on the equipment in the lab. The configuration output used in this lab is produced from 1721 series routers. Any other router used may produce slightly different output. The following steps are intended to be executed on each router unless specifically instructed otherwise. Start a HyperTerminal session as performed in the Establishing a HyperTerminal session lab. Note Go to the erase and reload instructions at the end of this lab. Perform those steps on all routers in this lab assignment before continuing. Step 1 Basic Router Configuration a. Configure the router. Connect the routers as shown in the diagram. This lab requires a null serial cable and two rollover or console cables. 1 - 5 CCNA 2 Routers and Routing Basics v - Lab Copyright 2003 Cisco Systems Inc. Step 2 Configure the name and passwords for Router 1 a. On Router 1 enter the global configuration mode and configure the hostname as shown in the chart. b. Configure the console virtual terminal and enable passwords. If there are any problems refer to the Lab Configuring Router Passwords. Step 3 Configure serial interface Serial 0 From global configuration mode configure serial interface Serial 0 on Router GAD. Refer to Interface Summary. GAD config interface serial 0 GAD config-if ip address GAD config-if clock rate 56000 GAD config-if no shutdown GAD config-if exit GAD config exit Note Once the interface configuration mode is entered note the IP address of the interface. Enter the subnet mask. Enter the clock rate only on the DCE side of the device. The command
