(2 marks) Question 5 (22 marks) This question covers subnetting networks covered in chapters 8 “IP addressing” & 9 “Subnetting IP network” A. A company is building a new network as shown in figure 1. (12 marks) Figure 1 network set-up The details of the topology of the network are as follows: • Net 1 LAN “Publishing LAN”: haves 67 PCs and one network printer connected to a switch. • Net 2 LAN “Advertising LAN”: have 27 PCS connected to a switch. • Net 3 WAN: router 1 “R1” is directly connected to router 2 “R2”. • Net 4 LAN “Server Farm”: have 8 servers connected to a switch. • Net 5 LAN “Wireless network”: can have at the same time up to 40 smart devices and up to 30 wireless devices connected to the access point • Net 6 LAN “Administration LAN”: has 17 PCs and one network printer connected to a switch. Subnet the address block 199.5.2.0/23 as appropriate to provide an efficient use of the addresses but at the same time providing sufficient addresses for all groups and links. Design an addressing scheme for the company by completing a copy of Table 2. You should complete one row for each different LAN/WAN links and use 199.5.2.0/23 as your starting address. You should use subnet 0. Notes: • Your choices should make the most economical use of the address range • You are not expected to send in a packet tracer file or to simulate the network in any way. You just need to copy and complete Table 2 • No IP address is assigned to the switch. • You can change the order to the Name of the LAN/WAN in table 2 Name of LAN/WAN Subnet address Address range Broadcast address Network suffix or mask Net 1 Net 2 Net 3 Net 4 Net 5 Net 6 Table 2 to be completed B. Implementing a Subnetted IPv6 Addressing Scheme Topology i. Determine the number of subnets needed. (4 marks) Start with the IPv6 subnet 2011:AOU:216A:04A4::/64 and assign it to the R1 LAN attached to GigabitEthernet 0/0, as shown in the Subnet Table. For the rest of the IPv6 subnets, increment the 2011:AOU:216A:04A4::/64 subnet address by 1 and complete the Subnet Table with the IPv6 subnet addresses. Subnet table Subnet Description Subnet address R1 G0/0 LAN 2011:AOU:216A:04A4::/64 R1 G0/1 LAN R2 G0/0 LAN R2 G0/1 LAN WAN Link ii. Assign IPv6 addressing to the routers (6 marks) • Assign the first IPv6 addresses to R1 for the two LAN links and the WAN link. • Assign the first IPv6 addresses to R2 for the two LANs. Assign the second IPv6 address for the WAN link. • Document the IPv6 addressing scheme in the Addressing Table. Addressing table Device Interface IPv6 Link-Local R1 G0/0 FE80::1 G0/1 FE80::1 S0/0/0 FE80::1 R2 G0/0 FE80::2 G0/1 FE80::2 S0/0/0 FE80::2 PC1 NIC Auto Config PC2 NIC Auto Config PC3 NIC Auto Config PC4 NIC Auto Config Question 6 (33 marks) This question allows you to demonstrate your ability to program a network of Cisco routers using packet tracer. The Packet tracer file for this question is T216AFA14TMA01Q6.pkt will be found on the AOULMS (Moodle). Configuration Configure your network as shown in figure 2 using (Command Line Interface) instructions. Your configuration should be complete as possible. Note1: the Packet Tracer file should be returned to a special forum which will be specified by your tutor. Note2: the packet tracer “configuration function” has been disabled so you will have to configure the routers through the CLI as if you were accessing them via the console interface or via telnet. Note3: do not forget to save the running configuration to the startup configuration Topology Diagram Figure 2 Network (Indicators have been turned off for clarity) Addressing Table Device Interface IP Address Subnet Mask Default Gateway R1_XXXXXX G0/0 172.190.5.1 255.255.255.0 N/A S0/0/0 192.192.0.1 255.255.255.252 N/A R2 G0/0 200.200.200.1 255.255.255.0 N/A G0/1 220.220.220.1 255.255.255.0 N/A S0/0/0 192.192.0.2 255.255.255.252 N/A S1_XXXXXX VLAN1 172.190.5.2 255.255.255.0 172.190.5.1 S2_XXXXXX VLAN1 172.190.5.3 255.255.255.0 172.190.5.1 P1 NIC 172.190.5.21 255.255.255.0 172.190.5.1 P2 NIC 172.190.5.22 255.255.255.0 172.190.5.1 P3 NIC 200.200.200.33 255.255.255.0 200.200.200.1 P4 NIC 220.220.220.44 255.255.255.0 220.220.220.1 L1 NIC 172.190.5.23 255.255.255.0 172.190.5.1 L2 NIC 172.190.5.124 255.255.255.0 172.190.5.1 Table 3 Note: XXXXXX is your ID (6 digits) Objectives • Perform basic device configuration task on a router R1 and switches S1 and S2 • Configure IP addressing setting on all network devices. • Verify Layer 3 connectivity.
