Pro Domain 1: Device Setup and Configuration

You are working with a single active router. You need to gather information about the router. In this lab, your task is to answer the following questions using the CLI: What is the IOS version? How much NVRAM is available on the router? How much DRAM does the router have? How many serial interfaces does the router have? What is the IOS version? 12.4 How much NVRAM (non-volatile RAM) is available on the router? 191K bytes of NVRAM How much DRAM does the router have? 256 MB How many serial interfaces does the router have? 4 You have just connected two routers through their serial ports in a back-to-back configuration. You've already configured IP addresses on the Fa0/0 and Fa0/1 interfaces for both routers and have configured a static route on each router for the networks accessible through the other router. You need to complete the configuration by configuring the serial link between the two routers. Remember that a 30-bit mask has a magic number of 4. Valid subnets are 192.168.2.0, 192.168.2.4, 192.168.2.8, etc. The seventh subnet is 192.168.2.24. The first valid address on that subnet is 192.168.2.25. The last valid address on that subnet is 192.168.2.26. A 30-bit mask uses a mask value of 255.255.255.252. In this lab, your task is to: Assign an IP address to each serial interface. Use the seventh subnet on network 192.168.2.0 using a 30-bit mask:For S0/0/0 on RouterA, assign the first address on the subnet.For S0/0/1 on RouterB, ass Find the DCE interface. Select RouterA. Press Enter to get started. At the RouterA> prompt, type show controllers s0/0/0 and press Enter. Select RouterB. Press Enter to get started. At the RouterB> prompt, type show controllers s0/0/1 and press Enter. RouterB has the DCE interface. Configure RouterB. At the RouterB> prompt, type enable and press Enter. At the RouterB# prompt, type config t and press Enter. At the RouterB(config)# prompt, type interface s0/0/1 and press Enter. At the RouterB(config-if)# prompt, type ip address 192.168.2.26 255.255.255.252 and press Enter. At the RouterB(config-if)# prompt, type clock rate 9600 and press Enter. At the RouterB(config-if)# prompt, type no shutdown and press Enter. Press Ctrl + Z. At the RouterB# prompt, type copy run start and press Enter. Press Enter to begin building the configuration. Configure RouterA. At the RouterA> prompt, type enable and press Enter. At the RouterA# prompt, type config t and press Enter. At the RouterA(config)# prompt, type interface s0/0/0 and press Enter. At the RouterA(config-if)# prompt, type ip address 192.168.2.25 255.255.255.252 and press Enter. At the RouterA(config-if)# prompt, type no shutdown and press Enter. Press Ctrl + Z. At the RouterA# prompt, type copy run start and press Enter. Press Enter to begin building the configuration. You manage the small branch office shown in the network diagram. You have connected all devices. Now you need to configure the hostname and interface descriptions on each Cisco device at the branch location. In this lab, your task is to: Change the hostname on the switch to Branch1. Change the router name to SFO. Configure the following interface descriptions: DeviceInterfaceDescriptiontext Branch1FastEthernet0/1Wrk1FastEthernet0/2Wrk2FastEthernet0/3Wrk3FastEthernet0/24Default gatewaySFOFastEthernet0/0Link to branch officeSerial0/1/0Link to main officeSerial0/1/1Link to internet Configure the hostname and the interface descriptions on the switch. Select Branch 1 in the diagram. Press Enter to get started. At the > prompt, type enable and press Enter. At the # prompt, type configure terminal and press Enter. At the (config)# prompt, type hostname Branch1 and press Enter. At the Branch1(config)# prompt, type interface FastEthernet0/1 and press Enter. At the Branch1(config-if)# prompt, type description Wrk1 and press Enter. At the Branch1(config-if)# prompt, type interface FastEthernet0/2 and press Enter. At the Branch1(config-if)# prompt, type description Wrk2 and press Enter. At the Branch1(config-if)# prompt, type interface FastEthernet0/3 and press Enter. At the Branch1(config-if)# prompt, type description Wrk3 and press Enter. At the Branch1(config-if)# prompt, type interface FastEthernet0/24 and press Enter. At the Branch1(config-if)# prompt, type description Default gateway and press Enter. At the Branch1(config-if)# prompt, type exit and press Enter. At the Branch1(config)# prompt, type exit and press Enter. At the Branch1# prompt, type copy running-config startup-config and press Enter. Press Enter. Configure the hostname and the interface descriptions on the router. Select SFO in the diagram.
