Network Design and Implementation Assessment 1.0 Phase1 Detailed Learning Objectives Upon completion of this case study, you will have demonstrated the ability to: Assign appropriate addresses to interfaces and host PCs in accordance with the topology diagram. Cable the network according to the diagram. Implement trunk links between switches. Implement VLANs within the switch network. Implement spanning tree protocol. Implement inter-VLAN routing. Implement Cisco HSRP. Implement Multi-area OSPF. Figure 1 – Topology DiagramScenario You are required to implement a switched network supporting four data VLANs for the network users. The network is designed with redundant links between switches, which must carry the VLANs to the layer 3 switches. Spanning tree and HSRP are required to provide L2 and L3 resiliency respectively, and multi-area OSPF is configured within the network core. Note: Save Packet Tracer frequently and keep text copies of your configuration to prevent disaster when the software crashes.
Task 1: Planning the addressing scheme. Step 1: Subnet the Address Space The 172.16.0.0 / 16 address space has been assigned to support a series of subnets as detailed in Table 1. You will also need to calculate appropriate contiguous address ranges for all VLANs, as well as for the links between DLS1, DLS2, R1, R2 and Core. Explain how you calculated the required subnets, and explain any assumptions made. VLAN ID Name Interfaces Number of Hosts 15 Staff Fa0/5-10 150 20 Students Fa0/11-15 1000 25 Registry Fa0/16-20 75 30 Voice Fa0/7-10, 16-20 225 99 Network Admin Fa0/24 (AS2 only) 10 Table 1 – Subnet RequirementsExplanation Total: ___________________15% Step 2: Document and assign interface and PC addresses Assign the last usable address in each subnet to the HSRP virtual IP address. Assign VLAN SVI addresses on DLS1 & DLS2 contiguous with the HSRP virtual IP address. All switch remote management will be via VLAN 99, so assign ALS1 a contiguous address following on from that assigned to DLS1 & DLS2 SVIs for VLAN 99. The Staff, Student and Voice VLANs will use DHCP to assign addresses, Registry and Network Admin will use static assignment. Assign appropriate IP addresses to the router interfaces from the assigned address space. Document the IP addressing plan, containing assigned IP addresses, masks, default gateways, etc in a tabular form within your report. Table Total: ___________________10% Step 3: Build the network in Packet Tracer Build the network shown in the topology diagram in Packet Tracer, and assign interface addresses as per Step 2.
