Perform The Following Stepsaccording To The Lab Layout Reference Diag

Implementing an effective network infrastructure requires precise configuration of switches and routers based on the provided laboratory layout reference diagram. This process involves initial setup, VLAN segmentation, trunk configuration, inter-VLAN routing, and routing protocols, ensuring seamless communication across different segments of the network.

Initial Switch Configuration

The configuration process begins with establishing the initial settings on the core switches, NYACCESS1 and NYCORE1. For NYACCESS1, the setup includes defining hostname, enabling SSH for secure remote management, setting passwords, and configuring management IP addresses on VLAN interfaces. Similarly, NYCORE1's initial configuration involves setting hostname, enabling secure access, and preparing the device for VLAN and trunk configurations. It is essential to configure management interfaces and verify connectivity at this stage.

For example, on NYACCESS1:

  • Set hostname to NYACCESS1
  • Configure VTY lines with passwords and access protocols
  • Assign management IP on VLAN 1 or dedicated management VLAN

On NYCORE1, similar steps apply, including setting hostname, passwords, and management IPs. These initial steps ensure foundational security and connectivity for subsequent configurations.

Router Configuration on NYEDGE1 and NYEDGE2

The next step involves configuring the routers, NYEDGE1 and NYEDGE2. Initial configurations should include setting hostnames, securing access, enabling interfaces, and assigning IP addresses based on the network design. Particular attention must be paid to enable routing protocols if necessary, or prepare static routes for specific destinations. These configurations allow routers to participate effectively within the network infrastructure and facilitate inter-VLAN communication via router on a stick.

VLAN and Trunk Configurations

To segment network traffic, VLANs are created on the switches. On NYACCESS, VLAN16 (Engineering), VLAN17 (Marketing), and VLAN18 (Sales) are configured. VLANs are assigned names for clarity and management ease. The Fa0/1 interface on NYACCESS is configured as a member of VLAN16, connecting end-user devices or access points.

The Switch Virtual Interface (SVI) for VLAN17 is created with IP address 192.168.17.10/24, providing the Layer 3 interface for that VLAN.

On NYCORE1, the same VLANs are created with identical numbering and naming. Trunk links are configured between NYACCESS1 and NYCORE1, and between NYCORE1 and NYEDGE1, allowing multiple VLANs to traverse singular physical links.

Example trunk configuration commands include:

  • Switchport trunk allowed vlan 16,17,18
  • Switchport mode trunk

Proper trunking ensures VLAN traffic can reach the appropriate devices across switches, vital for inter-VLAN routing and network segmentation.

Inter-VLAN Routing (Router on a Stick) on NYEDGE1

To enable communication between VLANs, a router-on-a-stick configuration is applied on NYEDGE1. This involves creating subinterfaces on the router’s interface connected to the trunk, each associated with a VLAN ID and assigned an IP address within that VLAN’s subnet. This setup allows NYEDGE1 to perform inter-VLAN routing without multiple physical interfaces, optimizing network design.

For example, subinterface configurations may be as follows:

interface GigabitEthernet0/1.16


encapsulation dot1Q 16


ip address 192.168.16.1 255.255.255.0


interface GigabitEthernet0/1.17


encapsulation dot1Q 17


ip address 192.168.17.1 255.255.255.0


interface GigabitEthernet0/1.18


encapsulation dot1Q 18


ip address 192.168.18.1 255.255.255.0

This configuration allows NYEDGE1 to route traffic between VLANs efficiently.

Routing Configuration

On NYEDGE1, a default route is established pointing to 192.168.254.2, assuming this is the upstream router or gateway for internet access or external network connectivity.

On NYEDGE2, a static route is created for network 192.168.16.0/24 via NYEDGE1's IP address within that subnet, enabling proper routing between devices.

Commands for setting a default route on NYEDGE1:

ip route 0.0.0.0 0.0.0.0 192.168.254.2

For NYEDGE2, ensure the static route points to NYEDGE1's IP address for the 192.168.16.0/24 network:

ip route 192.168.16.0 255.255.255.0 192.168.18.x

where 192.168.18.x is NYEDGE1's relevant interface IP address.

Verification and Documentation

After completing all configurations, it is essential to verify the setup with commands such as "show running-config", "show vlan brief", "show interfaces trunk", and "show ip route". This verification ensures all configurations are correctly applied and the network functions as intended.

Finally, copying the "show running-config" outputs from each device into a Microsoft Word document labeled "Final_Configuration" provides documentation for future reference and troubleshooting.

This comprehensive configuration and verification process establishes a secure, segmented, and efficient network infrastructure aligned with the referenced lab diagram.
