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. + +Open configuration windowa.^ Assign a device name to the switch. + +``` +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 switch to today’s time and date. +Note: Use the question mark (?) to help with the correct sequence of parameters needed to execute this +command. +j. Copy the running configuration to the startup configuration. +``` +### Step 7: Create VLANs on S1. + +Note: S2 is only configured with basic settings. +a. Create and name the required VLANs on switch 1 from the table above. +b. Configure and activate the management interface on S1 (VLAN 200) using the second IP address from +the subnet calculated earlier. Additionally, set the default gateway on S1. +c. Configure and activate the management interface on S2 (VLAN 1) using the second IP address from the +subnet calculated earlier. Additionally, set the default gateway on S +d. Assign all unused ports on S1 to the Parking_Lot VLAN, configure them for static access mode, and +administratively deactivate them. On S2, administratively deactivate all the unused ports. +Note: The interface range command is helpful to accomplish this task with as few commands as +necessary. +Close configuration windowOpen configuration window +Close configuration window + +### Step 8: Assign VLANs to the correct switch interfaces. + +a. Assign used ports to the appropriate VLAN (specified in the VLAN table above) and configure them for +static access mode. +Open configuration window + +``` +b. Verify that the VLANs are assigned to the correct interfaces. +Question: +Why is interface F0/5 listed under VLAN 1? +Type your answers here. +``` +### Step 9: Manually configure S1’s interface F0/5 as an 802.1Q trunk. + +``` +a. Change the switchport mode on the interface to force trunking. +b. As a part of the trunk configuration, set the native VLAN to 1000. +c. As another part of trunk configuration, specify that VLANs 100, 200, and 1000 are allowed to cross the +trunk. +d. Save the running configuration to the startup configuration file. +e. Verify trunking status. +Question: +At this point, what IP address would the PC’s have if they were connected to the network using DHCP? +``` +``` +Type your answers here. +``` +Close configuration window + + +## Part 2: Configure and verify two DHCPv4 Servers on R + +``` +In Part 2, you will configure and verify a DHCPv4 Server on R1. The DHCPv4 server will service two subnets, +Subnet A and Subnet C. +``` +### Step 1: Configure R1 with DHCPv4 pools for the two supported subnets. Only the DHCP Pool for + +### subnet A is given below + +Open configuration windowa.^ Exclude the first five useable addresses from e ach address pool.^ + +``` +b. Create the DHCP pool (Use a unique name for each pool). +c. Specify the network that this DHCP server is supporting. +d. Configure the domain name as ccna-lab.com +e. Configure the appropriate default gateway for each DHCP pool. +f. Configure the lease time for 2 days 12 hours and 30 minutes. +g. Next, configure the second DHCPv4 Pool using the pool name R2_Client_LAN and the calculated +network, default-router and use the same domain name and lease time from the previous DHCP pool. +``` +### Step 2: Save your configuration + +Save the running configuration to the startup configuration file. +Close configuration window + +### Step 3: Verify the DHCPv4 Server configuration + +``` +a. Issue the command show ip dhcp pool to examine the pool details. +b. Issue the command show ip dhcp bindings to examine established DHCP address assignments. +c. Issue the command show ip dhcp server statistics to examine DHCP messages. +``` +### Step 4: Attempt to acquire an IP address from DHCP on PC-A + +``` +a. Open a command prompt on PC-A and issue the command ipconfig /renew. +b. Once the renewal process is complete, issue the command ipconfig to view the new IP information. +c. Test connectivity by pinging R1’s G0/0/1 interface IP address. +``` +## Part 3: Configure and verify a DHCP Relay on R + +``` +In Part 3, you will configure R2 to relay DHCP requests from the local area network on interface G0/0/1 to the +DHCP server (R1). +``` +### Step 1: Configure R2 as a DHCP relay agent for the LAN on G0/0/ + +Open configuration windowa.^ Configure the ip helper-address^ command on G0/0/1 specifying R1’s G0/0/0 IP address.^ + +b. Save your configuration. +Close configuration window + +### Step 2: Attempt to acquire an IP address from DHCP on PC-B + +``` +a. Open a command prompt on PC-B and issue the command ipconfig /renew. +b. Once the renewal process is complete, issue the command ipconfig to view the new IP information. +c. Test connectivity by pinging R1’s G0/0/1 interface IP address. +d. Issue the show ip dhcp binding on R1 to verify DHCP bindings. +e. Issue the show ip dhcp server statistics on R1 and R2 to verify DHCP messages. +``` + +End of document + +
