One of the best ways to learn networking skills with Packet Tracer is by doing hands-on activities that challenge you to apply your knowledge and solve problems. One such activity is the PT Activity 451 Packet Tracer Skills Integration Challenge. This activity is designed to test your ability to create a new IPv4 addressing scheme that will accommodate four subnets using the 192.168.0.0/24 network. You will also need to finish the basic security settings and interface configurations on R1 router. Then, you will configure the SVI interface and basic security settings on switches S1, S2, and S3. Finally, you will verify your network by using various commands and tools.


In this article, we will guide you through the steps of completing the PT Activity 451 Packet Tracer Skills Integration Challenge. We will also provide some tips and explanations along the way. By the end of this article, you will have a better understanding of how to use Packet Tracer to create and manage a network.


IPv4 Addressing




The first step of the PT Activity 451 Packet Tracer Skills Integration Challenge is to create a new IPv4 addressing scheme that will accommodate four subnets using the 192.168.0.0/24 network. The IT department requires 25 hosts. The Sales department needs 50 hosts. The subnet for the rest of the staff requires 100 hosts. A Guest subnet will be added in the future to accommodate 25 hosts.


To create subnets that meet these host requirements, we need to use Variable Length Subnet Masking (VLSM). VLSM is a technique that allows us to divide a network into subnets of different sizes by using different subnet masks. This way, we can optimize the use of IP addresses and avoid wasting them.


To use VLSM, we need to follow these steps:


  • Identify the largest subnet requirement and assign it the first available subnet.



  • Identify the next largest subnet requirement and assign it the next available subnet.



  • Repeat this process until all subnets are assigned.



  • Calculate the subnet mask, broadcast address, and valid host range for each subnet.



  • Document the IPv4 addresses that have been assigned in the addressing table.



In our case, we have four subnets with different host requirements: Staff (100), Sales (50), IT (25), Guest (25). We will use VLSM to assign them the following subnets:


Subnet


Host Requirement


Subnet Mask


Subnet Address


Broadcast Address


Valid Host Range


Staff


100

192.168.0.193 - 192.168.0.222


Guest

192.168.0.224


192.168.0.255


192.168.0.225 - 192.168.0.254


We can document these subnets and their IPv4 addresses in the addressing table provided in the PT Activity 451 Packet Tracer Skills Integration Challenge file.


The next step is to configure the IPv4 addresses, subnet masks, and default gateways on the PCs and routers in the network.


To configure the IPv4 addresses on the PCs, we need to follow these steps:



  • Select a PC and click on the Desktop tab.



  • Click on IP Configuration and enter the IPv4 address, subnet mask, and default gateway for that PC according to the addressing table.



  • Click on FastEthernet and check that the port status is green.



  • Repeat this process for all the PCs in the network.



  • To configure the IPv4 addresses on the routers, we need to follow these steps:



  • Select a router and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Enter the interface configuration mode for each interface by typing interface [interface name].



  • Type ip address [IPv4 address] [subnet mask] to assign an IPv4 address and subnet mask to each interface.



  • Type no shutdown to activate each interface.



  • Type exit to return to the global configuration mode.



  • Type ip route 0.0.0 0 [next hop address] to configure a default route for each router.



  • Type end to return to the privileged EXEC mode.



  • Type wr mem to save the configuration.



  • Repeat this process for both routers in the network.



IPv6 Addressing




The second step of the PT Activity 451 Packet Tracer Skills Integration Challenge is to assign IPv6 unicast and link-local addresses and default gateways on the PCs and routers in the network.


To assign IPv6 unicast addresses, we need to use the global prefix 2001:db8:acad::/48 and append a subnet ID and an interface ID for each device.


To assign IPv6 link-local addresses, we need to use the prefix fe80::/10 and append an interface ID for each device.


To assign IPv6 default gateways, we need to use the link-local address of the router interface that is connected to the same subnet as the device.


We can document these IPv6 addresses in the addressing table provided in the PT Activity 451 Packet Tracer Skills Integration Challenge file.


To configure the IPv6 addresses on the PCs, we need to follow these steps:



  • Select a PC and click on the Desktop tab.



  • Select IP Configuration and click on IPv6 Configuration.



  • Select Static from the drop-down menu and enter the IPv6 address and the default gateway for that PC according to the addressing table.



  • Click on FastEthernet and check that the port status is green.



  • Repeat this process for all the PCs in the network.



  • To configure the IPv6 addresses on the routers, we need to follow these steps:



  • Select a router and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Enter the interface configuration mode for each interface by typing interface [interface name].



  • Type ipv6 address [IPv6 address] to assign an IPv6 unicast address to each interface.



  • Type ipv6 address [link-local address] link-local to assign an IPv6 link-local address to each interface.



  • Type no shutdown to activate each interface.



  • Type exit to return to the global configuration mode.



  • Type ipv6 route ::/0 [next hop address] to configure a default route for each router.



  • Type end to return to the privileged EXEC mode.



  • Type wr mem to save the configuration.



  • Repeat this process for both routers in the network.

Router Configurations




The third step of the PT Activity 451 Packet Tracer Skills Integration Challenge is to configure basic security settings, interfaces, and routing protocols on the R1 and Central routers.


To configure basic security settings on the routers, we need to follow these steps:



  • Select a router and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Type hostname [router name] to change the device name.



  • Type enable secret [password] to set a password for the privileged EXEC mode.



  • Type line console 0 to enter the console line configuration mode.



  • Type password [password] to set a password for the console access.



  • Type login to enable password checking.



  • Type exit to return to the global configuration mode.



  • Type line vty 0 4 to enter the virtual terminal line configuration mode.



  • Type password [password] to set a password for the remote access.



  • Type login to enable password checking.



  • Type exit to return to the global configuration mode.



  • Type banner motd # [message] # to set a message of the day banner that will be displayed when someone logs in.



  • Type end to return to the privileged EXEC mode.



  • Type wr mem to save the configuration.



  • Repeat this process for both routers in the network.



To configure interfaces on the routers, we have already done that in the previous step when we assigned IPv4 and IPv6 addresses. However, we can also add some descriptions to each interface to make them more identifiable. To do that, we need to follow these steps:



  • Select a router and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Enter the interface configuration mode for each interface by typing interface [interface name].



  • Type description [text] to add a description to each interface.



  • Type exit to return to the global configuration mode.



  • Type wr mem to save the configuration.



  • Repeat this process for both routers in the network.



To configure routing protocols on the routers, we need to use Enhanced Interior Gateway Routing Protocol (EIGRP) as specified in the PT Activity 451 Packet Tracer Skills Integration Challenge file. EIGRP is a dynamic routing protocol that can exchange routing information between routers and automatically update their routing tables. To configure EIGRP, we need to follow these steps:



  • Select a router and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Type router eigrp [autonomous system number] to enable EIGRP and enter the router configuration mode. The autonomous system number is a unique identifier for the network and must be the same for all routers that participate in EIGRP.



  • Type network [network address] [wildcard mask] to specify which interfaces will participate in EIGRP. The network address and wildcard mask are used to match the interfaces that belong to the same network.



  • Type no auto-summary to disable automatic summarization of routes. This will allow EIGRP to advertise the exact subnet masks of each network.



  • Type exit to return to the global configuration mode.



  • Type wr mem to save the configuration.



  • Repeat this process for both routers in the network.



Switch Configurations




The fourth step of the PT Activity 451 Packet Tracer Skills Integration Challenge is to configure device name, password, banner, and SVI interface on switches S1, S2, and S3.


To configure device name, password, and banner on the switches, we need to follow the same steps as we did for the routers. However, we need to use different passwords and banners for each switch.


To configure SVI interface on the switches, we need to create a virtual interface that will act as the default gateway for the devices connected to the switch. To do that, we need to follow these steps:



  • Select a switch and click on the CLI tab.



  • Enter the privileged EXEC mode by typing enable.



  • Enter the global configuration mode by typing configure terminal.



  • Type interface vlan 1 to enter the interface configuration mode for VLAN 1.



  • Type ip address [IPv4 address] [subnet mask] to assign an IPv4 address and subnet mask to VLAN 1.



  • Type ipv6 address [IPv6 address] to assign an IPv6 unicast address to VLAN 1.



  • Type ipv6 address [link-local address] link-local to assign an IPv6 link-local address to VLAN 1.



  • Type no shutdown to activate VLAN 1.



  • Type exit to return to the global configuration mode.



  • Type wr mem to save the configuration.



  • Repeat this process for all switches in the network.



Verification and Testing




The final step of the PT Activity 451 Packet Tracer Skills Integration Challenge is to verify and test the network by using various commands and tools. We need to make sure that all devices can communicate with each other using both IPv4 and IPv6 protocols. We also need to check that the access lists are working properly and filtering traffic as intended.


To verify and test the network, we can use the following commands and tools:



  • Ping: This command sends an echo request packet to a destination device and waits for an echo reply packet. It can be used to test connectivity and latency between devices. We can use ping with both IPv4 and IPv6 addresses.



  • Traceroute: This command traces the path that a packet takes from a source device to a destination device. It can be used to identify the routers and interfaces that are involved in forwarding packets. We can use traceroute with both IPv4 and IPv6 addresses.



  • Show ip route: This command displays the IPv4 routing table of a router or a switch. It can be used to check which networks are reachable and which routing protocols are being used.



  • Show ipv6 route: This command displays the IPv6 routing table of a router or a switch. It can be used to check which networks are reachable and which routing protocols are being used.



  • Show ip interface brief: This command displays a summary of information about the IPv4 interfaces of a router or a switch. It can be used to check the status, protocol, and IP address of each interface.



  • Show ipv6 interface brief: This command displays a summary of information about the IPv6 interfaces of a router or a switch. It can be used to check the status, protocol, and IP address of each interface.



  • Show access-lists: This command displays information about the access lists that are configured on a router or a switch. It can be used to check the criteria and actions of each access list entry.



  • Show ip access-lists: This command displays information about the IPv4 access lists that are configured on a router or a switch. It can be used to check the criteria and actions of each access list entry.



  • Show ipv6 access-lists: This command displays information about the IPv6 access lists that are configured on a router or a switch. It can be used to check the criteria and actions of each access list entry.



  • Packet Capture: This tool allows us to capture and analyze the packets that are sent and received by a device. It can be used to inspect the details of each packet, such as the source and destination addresses, protocols, ports, and payload. We can use packet capture with both IPv4 and IPv6 packets.



We can use these commands and tools on any device in the network by selecting it and clicking on the CLI tab or the Packet Capture tab. We can also use the Simulation mode to control the flow of packets and observe their behavior.
