We will also configure the devices and interfaces with some basic commands and protocols. We will also test our network functionality with some tools and commands.


How to create a LAN with switches and PCs?




A LAN (Local Area Network) is a network that connects devices within a small area, such as a home, office, or school. A switch is a device that connects multiple devices on a LAN and forwards packets based on their MAC addresses. A PC (Personal Computer) is a device that can send and receive data on a network.


To create a LAN with switches and PCs, you need to follow these steps:



  • Add two switches and four PCs to your workspace. You can use the Common Devices tab and the End Devices tab to access these devices.



  • Connect the switches with each other using a crossover cable. You can use the Connections tab and the Auto Connect tool to select the appropriate cable.



  • Connect each PC to a switch using a straight-through cable. You can use the Connections tab and the Auto Connect tool to select the appropriate cable.



  • Configure each PC with an IP address, a subnet mask, and a default gateway. You can use the Config tab and the IP Configuration tool to enter these values. For example, you can use the following values:



  • PC0: IP address: 192.168.1.10, Subnet mask: 255.255.255.0, Default gateway: 192.168.1.1



  • PC1: IP address: 192.168.1.11, Subnet mask: 255.255.255.0, Default gateway: 192.168.1.1



  • PC2: IP address: 192.168.2.10, Subnet mask: 255.255.255.0, Default gateway: 192.168.2.1



  • PC3: IP address: 192.168.2.11, Subnet mask: 255.255.255.0, Default gateway: 192.168.2.1



  • Test your network functionality by pinging from one PC to another PC on the same or different subnet. You can use the Desktop tab and the Command Prompt tool to enter the ping command followed by the IP address of the destination PC.



How to create a WAN with routers and PCs?




A WAN (Wide Area Network) is a network that connects devices across a large area, such as a city, country, or world. A router is a device that connects multiple networks and forwards packets based on their IP addresses.


To create a WAN with routers and PCs, you need to follow these steps:



  • Add two routers and four PCs to your workspace. You can use the Common Devices tab and the End Devices tab to access these devices.



  • Connect each router to two PCs using straight-through cables.



  • Connect the routers with each other using a serial cable.



  • Configure each PC with an IP address, a subnet mask, and a default gateway.



  • Configure each router interface with an IP address and a subnet mask.



  • Configure static routes on each router to reach the other router's network.



  • Test your network functionality by pinging from one PC to another PC on the same or different network.



How to create a wireless network with access points and laptops?




A wireless network is a network that connects devices without using cables, but using radio waves instead. An access point is a device that acts as a bridge between wired and wireless networks and allows wireless devices to join the network.


To create a wireless network with access points and laptops, you need to follow these steps:



  • Add two access points and four laptops to your workspace.



  • Connect each access point to a switch using straight-through cables.



  • Connect each switch to a router using straight-through cables.



  • Configure each laptop with an IP address, a subnet mask, and a default gateway.



  • Configure each access point with an IP address, a subnet mask, a default gateway, and a SSID (Service Set Identifier).



  • Connect each laptop to an access point using the Connect tool.



  • Test your network functionality by pinging from one laptop to another laptop on the same or different wireless network.



Advanced network scenarios with Cisco Packet Tracer




In this section, we will show you how to create some advanced network scenarios with Cisco Packet Tracer. We will use the devices and connections that we have already added to our project. We will also configure the devices and interfaces with some advanced commands and protocols. We will also test our network functionality with some tools and commands.


How to use VLANs and trunking?




A VLAN (Virtual Local Area Network) is a logical grouping of devices on a LAN that share the same broadcast domain. Trunking is a technique that allows multiple VLANs to travel across a single link between switches or routers.


To use VLANs and trunking, you need to follow these steps:



  • Create two VLANs on each switch using the CLI (Command Line Interface) tool. You can use the following commands:



  • enable: to enter the privileged mode



  • configure terminal: to enter the global configuration mode



  • vlan 10: to create VLAN 10



  • name Sales: to assign a name to VLAN 10



  • vlan 20: to create VLAN 20



  • name Marketing: to assign a name to VLAN 20



  • exit: to exit the VLAN configuration mode



  • Assign each switch port to a VLAN using the CLI tool. You can use the following commands:



  • interface fastEthernet 0/1: to enter the interface configuration mode for port 0/1



  • switchport mode access: to set the port mode to access



  • switchport access vlan 10: to assign the port to VLAN 10



  • exit: to exit the interface configuration mode



  • Repeat these steps for other ports and VLANs as per your network design.



  • Configure trunking on the link between the switches using the CLI tool. You can use the following commands:



  • interface fastEthernet 0/24: to enter the interface configuration mode for port 0/24



  • switchport mode trunk: to set the port mode to trunk



  • switchport trunk allowed vlan 10,20: to allow only VLAN 10 and 20 on the trunk link



  • exit: to exit the interface configuration mode



  • Repeat these steps for the other switch.



  • Test your network functionality by pinging from one PC to another PC on the same or different VLAN.



How to use routing protocols and static routes?




A routing protocol is a set of rules that determines how routers exchange information and select the best paths for data transmission. A static route is a manually configured route that specifies the next-hop address or interface for a destination network.


To use routing protocols and static routes, you need to follow these steps:



  • Choose a routing protocol that suits your network design. You can use one of the following routing protocols:



  • RIP (Routing Information Protocol): a distance-vector routing protocol that uses hop count as the metric.



  • EIGRP (Enhanced Interior Gateway Routing Protocol): a hybrid routing protocol that uses bandwidth and delay as the metrics.



  • OSPF (Open Shortest Path First): a link-state routing protocol that uses cost as the metric.



  • Configure the routing protocol on each router using the CLI tool. You can use the following commands:



  • enable: to enter the privileged mode



  • configure terminal: to enter the global configuration mode



  • router rip: to enable RIP on the router



  • network 192.168.1.0: to advertise the network 192.168.1.0/24 to other routers



  • network 192.168.2.0: to advertise the network 192.168.2.0/24 to other routers



  • exit: to exit the router configuration mode



  • Repeat these steps for other routers and networks as per your network design.



  • Configure static routes on each router using the CLI tool. You can use the following commands:



  • enable: to enter the privileged mode



  • configure terminal: to enter the global configuration mode



  • ip route 192.168.3.0 255.255.255.0 192.168.2.2: to create a static route for the network 192.168.3.0/24 with the next-hop address 192.168.2.2



  • exit: to exit the global configuration mode



  • Repeat these steps for other routers and networks as per your network design.



  • Test your network functionality by pinging from one PC to another PC on the same or different network.



How to use NAT and DHCP?




NAT (Network Address Translation) is a technique that allows private IP addresses to be translated into public IP addresses when accessing the Internet or other networks. DHCP (Dynamic Host Configuration Protocol) is a protocol that allows devices to obtain IP addresses and other network settings automatically from a server.


To use NAT and DHCP, you need to follow these steps:



  • Add an ISP (Internet Service Provider) router and a cloud to your workspace. You can use the Common Devices tab and the WAN Emulation tab to access these devices.



  • Connect the ISP router to the cloud using a serial cable.



  • Connect one of your routers to the ISP router using a straight-through cable.



  • Configure the ISP router with an IP address, a subnet mask, and a default gateway for its interfaces using the CLI tool.



  • Configure NAT on your router using the CLI tool. You can use the following commands:



  • enable: to enter the privileged mode



  • configure terminal: to enter the global configuration mode



  • interface fastEthernet 0/0: to enter the interface configuration mode for port 0/0



  • ip nat inside: to designate this interface as inside NAT



  • exit: to exit the interface configuration mode



  • interface fastEthernet 0/1: to enter the interface configuration mode for port 0/1



  • ip nat outside: to designate this interface as outside NAT



  • exit: to exit the interface configuration mode



  • access-list 1 permit 192.168.0.0 0.0.255.255: to create an access list that permits all traffic from your private network



  • ip nat inside source list 1 interface fastEthernet 0/1 overload: to create a dynamic NAT pool that uses port address translation (PAT) on the outside interface



  • exit: to exit the global configuration mode



  • Configure DHCP on your router using the CLI tool. You can use the following commands:



  • enable: to enter the privileged mode



  • configure terminal: to enter the global configuration mode



  • ip dhcp pool LAN: to create a DHCP pool named LAN



  • network 192.168.1.0 255.255.255.0: to specify the network and subnet mask for the DHCP pool



  • default-router 192.168.1.1: to specify the default gateway for the DHCP pool



  • dns-server 8.8.8.8: to specify the DNS server for the DHCP pool



  • exit: to exit the DHCP pool configuration mode
