Hierarchical IP scheme and VLAN

Create an IP Scheme and VLANS.

I suggest use the table below to create your hierarchical IP addressing scheme.

Create VLAN: In creating VLAN, I will suggest use organizational structure model for simplicity.

Examples: VPOPRVLAN1, VPOPRVLAN2

High Level Diagram:

Drawing a network topology diagram is the most challenging task. To overcome this challenge, we need to use Cisco modular technology in upgrading the network in other words top down design approach. The top design approach starts with Application, Devices and infrastructure. You will also use the same approach in designing WWTC network. Select all the applications for the network. Then select the devices needed to run these applications. Now you are ready creating network topology diagram. Since, in WWTC network we have one floor, so all of our devices, application and infrastructure will reside in one floor.

Create subnets. Generally subnet matches organizational structure. Also, in a large network to increase performance or for security reasons, subnets are created. Furthermore to accommodate the need of a department, the subnets can be subnetted further or VLANs are created or both. Every organization have subnets and VLANs. Let us say we need 20 VLANs, which will serve client’s requirements, performance and security of the network. Assign these VLANs to switches. For example; you need 3 switches to host 3 VLANs for VPOPR. The diagram below depict the scenario.
