You are a Network Architect for a Network Design Consulting (NDC) company. The company uses the Campus Design proposed by Cisco (see Fig. 1) to set networks. You have been given the assignment of designing a network for a small university. The university will have four buildings, and each building will have three floors. Each floor will have two computer labs with 32 computers for student use. Each lab will be on its own subnet/VLAN. In addition to student PCs, there will be one printer/copier, one Voice-over-IP phone (VoIP), and one faculty workstation in each lab. The printer/copiers in a lab should be accessible to all the users on all the floors of a building. (Hint: Should the printers/copiers be on a subnet/VLAN of their own?). All the VoIP phones and faculty workstations in a single building will be on a subnet/VLAN of their own. Each lab will have physical security gateway on each floor that will require one PoE (Power-over-Ethernet) data drop. All the security gateways on all the buildings will be on a single subnet/VLAN. There will be one DHCP server (to assign IP addresses to computers, VoIP phones, faculty workstations and security gateways). There will be one web server, and one DNS server for the entire university network. All the servers will be assigned static IP addresses and will be part of same subnet/VLAN. Each floor of a building will have an IDF. All the IDFs will be connected to an MDF in the building to host the networking equipment. Entrance facility (Demarcation Point) point will be in one of the three buildings, you can choose the building to host the entrance facility, but you must provide a reason for the selection. In the final design, computers in one lab must be able to ping computers in all other labs and among themselves. Other requirements: All the users will be running application that will require continuous and uninterrupted network access. Therefore, physical redundancy and use of protocols like HSRP, LACP, etc. is a must. Security is important, so switchport security is a must. To easily manage VLANs, the university will be using VTP protocol. Required Tasks: 1. Propose an IP addressing scheme using VLSM. You are allowed to use only one Class B network ID as described in RFC 1918. 2. Configure the entire network in Packet Tracer with PCs, phones, printers, DHCP servers, web servers, DNS servers, InterVLAN routing, HSRP, LACP, VLANs, switchport security, and any other protocols and hardware required by the clients. 3. If deemed necessary, client may add further requirements so keep your design flexible. 4. The final submission must include the designed IP addressing scheme, a packet tracer file with the configured design. The proposal must also include: • The number of switches and data drops required • Number of routers and DHCP servers required • Number of VLANs required and subnetting calculations
