Project Descriptionxumuc Has Wan Links In Place At Their New Location

Project Description XUMUC has WAN links in place at their new location in the Columbia Region. XUMUC currently has 2 other regional locations, in Largo and Laurel. Originally, XUMUC was only located in one region (Largo). The previous consultant did a poor job with the integration, resulting in a poor IP address scheme. As a result, routing tables at the summarization points at the Largo campus are very large.

In addition, no VLAN structure was developed to isolate broadcast traffic and there has been some concern that the WAN transport was not able to accommodate the network traffic. Finally, all addresses in the network are statically assigned resulting in high administrative overhead, even when minor changes are implemented. For the next expansion phase, XUMUC would like this changed to lower administrative overhead. There are 4 main departments in XUMUC: sales, finance, human resources, and research and development. For assigning IP addresses you can pick any one from the following network addresses.

172.16.0.0/16

1.0.0.0/8

2.0.0.0/8

3.0.0.0/8

4.0.0.0/8

10.0.0.0/8

5.0.0.0/8

6.0.0.0/8

7.0.0.0/8

8.0.0.0/8

Assignment Instructions

Develop a comprehensive network design plan that addresses the current issues at XUMUC. Your plan should include the creation of VLANs to isolate broadcast traffic effectively, strategies to reduce WAN traffic, and a new IP addressing scheme that facilitates summarization at key routing points. Provide detailed IP addressing tables, including specific subnet allocations for each location, and update the network diagram with summarized routes at each router and link addresses. Your report must follow APA style, be between 3 to 5 pages in the main body, and include a cover page, executive summary, table of contents, and references. Clearly document assumptions and technical details, and ensure your solution minimizes administrative overhead while enhancing network efficiency and scalability.

Paper For Above instruction

The network infrastructure of the University of Maryland University College (XUMUC) requires significant optimization to address inefficiencies stemming from prior poor planning, a lack of VLAN segmentation, high administrative overhead due to static IP allocation, and inefficient routing tables caused by inadequate summarization. This paper proposes a comprehensive design overhaul encompassing VLAN implementation, a scalable IP addressing scheme, and route summarization to streamline operations across multiple campuses—Largo, Laurel, and Columbia—and remote offices.

Analysis of Current Network Issues

Initially, XUMUC's network suffered from a poor IP address scheme resulting from previous consultancy efforts. Large routing tables, particularly at the Largo campus, impair network performance and scalability. The absence of VLANs allows broadcast traffic to pervade the entire network, creating congestion and potential security concerns. Furthermore, the static nature of IP assignment adds administrative overhead, complicating network management as the university expands.

WAN links are currently under strain, potentially due to unoptimized traffic flows and lack of traffic prioritization or segmentation. These issues collectively hinder operational efficiency and threaten future scalability.

Designing a VLAN Structure

Implementing VLANs is essential for isolating broadcast traffic and improving security. In this scenario, the primary VLANs correspond to the main departments: sales, finance, HR, and R&D. Each department receives its VLAN, facilitating traffic segmentation. A common management VLAN can also be established for administrative purposes. VLAN IDs can be assigned as follows:

  • VLAN 10 - Sales
  • VLAN 20 - Finance
  • VLAN 30 - Human Resources
  • VLAN 40 - Research & Development
  • VLAN 99 - Management

This segmentation isolates departmental broadcast domains, reduces overall broadcast traffic, and enhances security by limiting lateral movement within the network.

IP Addressing Scheme and Route Summarization

Selecting an appropriate address block from the provided options is critical. The university's size suggests using the 172.16.0.0/16} network due to its flexibility and ample host capacity. The proposed subnet allocations are as follows:

  • Largo Campus: 172.16.0.0/21 (2048 addresses, enough for 1290 required)
  • Laurel Campus: 172.16.8.0/22 (1024 addresses, sufficient for 441 devices)
  • Columbia Campus: 172.16.12.0/23 (512 addresses, adequate for 329 devices)
  • Remote Offices: 172.16.14.0/24 (256 addresses)

For route summarization, aggregate addressing at the regional hubs is vital. For example:

  • Laurel Region: 172.16.8.0/21, summarizing the Laurel Campus and remote office as a single route.
  • Columbia Region: 172.16.12.0/22, summarizing the Columbia Campus and remote office.

Routing protocols like OSPF or EIGRP should be configured to advertise these summarized routes at each regional hub, reducing the size of routing tables significantly.

Updating Network Diagram & Link Addresses

The revised diagram should depict the summarized address blocks at each router, with links configured using the subnet addresses, ensuring clear route advertisement boundaries. For instance, the router at Largo would have a route advertisement for 172.16.0.0/21, covering all local subnets and remote sites within the region.

Reduction of Administrative Overhead

Transitioning from static IP assignments to DHCP with address pools aligned with subnets simplifies device management. VLAN segmentation coupled with dynamic routing enhances network flexibility, allowing network administrators to make minor network changes without extensive manual reconfiguration.

Implementing route summarization reduces routing complexity, especially at the core and distribution layers, improving network performance and scalability as new sites are added.

Conclusion

This proposed restructuring addresses the existing network deficiencies at XUMUC by creating a scalable, secure, and manageable network architecture. Implementing VLANs to isolate traffic, adopting a hierarchical IP addressing scheme with route summarization, and transitioning to dynamic addressing significantly improve operational efficiency, reduce administrative overhead, and prepare the network for future expansion. These strategies collectively ensure that XUMUC can sustain growth while maintaining high-performance standards across all campuses and sites.
