Cisco CCNA 200-301 Configuration Labs with Packet Tracer

Introduction:

Aspiring network engineers pursuing the Cisco Certified Network Associate (CCNA) certification need hands-on practice to reinforce their understanding of network configuration. Cisco Packet Tracer is a powerful simulation tool that allows users to create and configure virtual networks.

Lab 1: Configuring VLANs and Trunking

In this lab, we will focus on configuring VLANs and trunking on Cisco switches. A VLAN (Virtual Local Area Network) allows you to logically divide a switch into multiple broadcast domains, improving network performance and security. Trunking enables the transmission of multiple VLANs over a single link between switches.

Switch(config)# interface fastEthernet 0/1
Switch(config-if)# switchport trunk encapsulation dot1q
Switch(config-if)# switchport mode trunk
Switch(config-if)# exit

Switch(config)# interface fastEthernet 0/2
Switch(config-if)# switchport mode access
Switch(config-if)# switchport access vlan 10
Switch(config-if)# exit

Lab 2: Configuring Inter-VLAN Routing

In this lab, we will configure inter-VLAN routing using a router. Inter-VLAN routing allows communication between different VLANs by routing traffic through a router. This lab will help you understand how to configure VLAN interfaces on the router and enable routing between them.

Router(config)# interface gigabitEthernet 0/0
Router(config-if)# no shutdown
Router(config-if)# exit

Router(config)# interface gigabitEthernet 0/0.10
Router(config-subif)# encapsulation dot1Q 10
Router(config-subif)# ip address 192.168.10.1 255.255.255.0
Router(config-subif)# exit

Router(config)# interface gigabitEthernet 0/0.20
Router(config-subif)# encapsulation dot1Q 20
Router(config-subif)# ip address 192.168.20.1 255.255.255.0
Router(config-subif)# exit

Lab 3: Configuring DHCPv4 and DHCPv6

In this lab, we will configure Dynamic Host Configuration Protocol (DHCP) to automatically assign IP addresses to network devices. DHCPv4 is used for IPv4 networks, while DHCPv6 is used for IPv6 networks. This lab will help you understand how to configure DHCP pools and relay agents.

Router(config)# ip dhcp pool VLAN10
Router(dhcp-config)# network 192.168.10.0 255.255.255.0
Router(dhcp-config)# default-router 192.168.10.1
Router(dhcp-config)# exit

Router(config)# ipv6 dhcp pool VLAN20
Router(config-dhcpv6)# address prefix 2001:db8:10::/64
Router(config-dhcpv6)# dns-server 2001:db8:10::1
Router(config-dhcpv6)# exit

Lab 4: Configuring OSPFv2 and OSPFv3

In this lab, we will configure Open Shortest Path First (OSPF) routing protocol for both IPv4 and IPv6. OSPF is a link-state routing protocol used to exchange routing information between routers. This lab will help you understand how to configure OSPFv2 and OSPFv3, and establish neighbor relationships.

Router(config)# router ospf 1
Router(config-router)# network 192.168.0.0 0.0.0.255 area 0
Router(config-router)# exit

Router(config)# ipv6 router ospf 1
Router(config-rtr)# network 2001:db8:10::/64 area 0
Router(config-rtr)# exit

Conclusion:

These labs provide hands-on practice for configuring VLANs, trunking, inter-VLAN routing, DHCP, and OSPF. As you work through these labs using Cisco Packet Tracer, you will gain valuable experience in configuring and troubleshooting network devices, which is essential for the CCNA 200-301 exam. Remember to experiment with different network topologies and scenarios to further enhance your skills.
