Network Architecture Design

As you work through the various elements it is important to have structure in your workflow.

---

An example of a design document structure is presented below:

1. Introduction
2. Requirements for the Design
3. Existing Infrastructure
   • Layer 1 Topology
   • Layer 2 Topology
   • Layer 3 Topology
   • Audit Results
   • Recommendations
4. Intelligence Services
   • Applications
   • Services
   • Analysis
   • Recommendations
5. Solution Design
   • Design Summary
   • Design Details
   • Implementation Details
   • Recommendations
6. Prototype Network
   • Prototype Details
   • Prototype Results
   • Recommendations
7. Implementation Plan

Using this you could create checklists such as:

• Network Analysis
• Constraints
• Assumptions
• Drawbacks
• Risk Assessment

##Checklist

Technologies Implemented

• Hierarchical Network Design.
• Connecting Networking devices with Correct cabling.
• Creating VLANs and assigning ports VLAN numbers.
• Subnetting and IP Addressing.
• Configuring Inter-VLAN Routing (Router on a stick).
• Configuring DHCP Server (Router as the DHCP Server).
• Configuring SSH for secure Remote access.
• Configuring RIPv2 as the routing protocol.
• Configuring switchport security or Port-Security on the switches.
