Lab - Implement DHCPv4 Part 2: Configure and verify two DHCPv4 Servers on R1 Part 3: Configure and verify a DHCP Relay on R2 Background / Scenario The Dynamic Host Configuration Protocol (DHCP) is a network protocol that lets network administrators manage and automate the assignment of IP addresses. Without DHCP for IPv4, the administrator must manually assign and configure IP addresses, preferred DNS servers, and default gateways. As the network grows in size, this becomes an administrative problem when devices are moved from one internal network to another. In this scenario, the company has grown in size, and the network administrators can no longer assign IP addresses to devices manually. Your job is to configure the R1 router to assign IPv4 addresses on two different subnets. Note : The routers used with CCNA hands-on labs are Cisco 4221 with Cisco IOS XE Release 16.9.4 (universalk9 image). The switches used in the labs are Cisco Catalyst 2960s with Cisco IOS Release 15.2(2) (lanbasek9 image). Other routers, switches, and Cisco IOS versions can be used. Depending on the model and Cisco IOS version, the commands available and the output produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at the end of the lab for the correct interface identifiers. Note : Ensure that the routers and switches have been erased and have no startup configurations. If you are unsure contact your instructor. Required Resources  2 Routers (Cisco 4221 with Cisco IOS XE Release 16.9.4 universal image or comparable)  2 Switches (Cisco 2960 with Cisco IOS Release 15.2(2) lanbasek9 image or comparable)  2 PCs (Windows with a terminal emulation program, such as Tera Term)  Console cables to configure the Cisco IOS devices via the console ports  Ethernet cables as shown in the topology Instructions Part 1: Build the Network and Configure Basic Device Settings In Part 1, you will set up the network topology and configure basic settings on the PC hosts and switches. Step 1: Establish an addressing scheme Subnet the network 192.168.1.0/24 to meet the following requirements: a. One subnet, “Subnet A”, supporting 58 hosts (the client VLAN at R1). Subnet A: Type your answer(s) here. Type your answers here. Record the first IP address in the Addressing Table for R1 G0/0/1.100. b. One subnet, “Subnet B”, supporting 28 hosts (the management VLAN at R1). Subnet B: Type your answer(s) here. Type your answers here. Record the first IP address in the Addressing Table for R1 G0/0/1.200. Record the second IP address in the Address Table for S1 VLAN 200 and enter the associated default gateway. Type your answer(s) here.  2017 - 2020 Cisco and/or its affiliates. All rights reserved. Cisco Public Page 2 of 6 www.netacad.com

Lab - Implement DHCPv4 c. One subnet, “Subnet C”, supporting 12 hosts (the client network at R2). Subnet C: Type your answer(s) here. Record the first IP address in the Addressing Table for R2 G0/0/1. Record the second IP address in the Address Table for S2 VLAN 1 and enter the associated default gateway. Type your answer(s) here. Step 2: Cable the network as shown in the topology. Attach the devices as shown in the topology diagram, and cable as necessary. Step 3: Configure basic settings for each router. a. Assign a device name to the router. Open configuration window b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names. c. Assign class as the privileged EXEC encrypted password. d. Assign cisco as the console password and enable login. e. Assign cisco as the VTY password and enable login. f. Encrypt the plaintext passwords. g. Create a banner that warns anyone accessing the device that unauthorized access is prohibited. h. Save the running configuration to the startup configuration file. i. Set the clock on the router to today’s time and date. Note : Use the question mark ( ? ) to help with the correct sequence of parameters needed to execute this command. Step 4: Configure Inter-VLAN Routing on R1 a. Activate interface G0/0/1 on the router. b. Configure sub-interfaces for each VLAN as required by the IP addressing table. All sub-interfaces use 802.1Q encapsulation and are assigned the first usable address from the IP address pool you have calculated. Ensure the sub-interface for the native VLAN does not have an IP address assigned. Include a description for each sub-interface. c. Verify the sub-interfaces are operational. Step 5: Configure G0/0/1 on R2, then G0/0/0 and static routing for both routers a. Configure G0/0/1 on R2 with the first IP address of Subnet C you calculated earlier. b. Configure interface G0/0/0 for each router based on the IP Addressing table above. c. Configure a default route on each router pointed to the IP address of G0/0/0 on the other router. d. Verify static routing is working by pinging R2’s G0/0/1 address from R1. e. Save the running configuration to the startup configuration file. Close configuration window Step 6: Configure basic settings for each switch. a. Assign a device name to the switch. Open configuration window b. Disable DNS lookup to prevent the router from attempting to translate incorrectly entered commands as though they were host names.  2017 - 2020 Cisco and/or its affiliates. All rights reserved.
