Network technology Paper 2

  1. 1. Network Technology Q1. A class less: Domain Routing (CIDR) address (8.0.0.0/7) has been assigned to the network below: London Birmingham 256 hosts 60 host Manchester 127 host a. Employ VLSM to design a complete addressing scheme for the network. Produce a table for your design and populate it with address and subnet masks in forward slash notation format. b. Label all network segments with Broadcast and full range of address. c. Explain some benefits of employing VLSM in network design.

Structure Performance Management Scalable VLSM 1. Reduces address space wastage 2. Reduce size of routing tables. 8.0.3.1 8.0.3.62 BC.63 8.0.3.64/26 8.0.3.128/26 8.0.3.192/26
  5. 5. Q2. Determine the route to a destination network given that packets to the remote network pass through two fast Ethernet ports. The delay of a fast Ethernet port is 100MS 256 X [ 107/105 + 200/10 ] 256X120 = 30720 Show IP route C 192.168.1.0/24 is a directly connected Fast Ethernet 0/0 C 192.168.3.0/24 is a directly connected Fast Ethernet 0/1 D 192.168.2.0/24 [90/30720] via is a directly connected Fast Ethernet 0/0 EIGRP AA Metric = Administrative distance a. Determine the dynamic routing protocol active on the router. b. Sketch the network topology using the information in the table. Label all network segments with their network address. Indicate suitable IP addresses for all interfaces on connected networks.

CF7C. 4B78 Source MAC = 00E0.F75A.7604 Destination MAC = 00ED. F75A.7601 Destination MAC = 00ED. F983.B5A6 LAYER 1 PORT Fast Ethernet 0/0 LAYER 1 PORT Fast Ethernet 0/1 (a) Sketch the network diagram using the data in the tables above. Assume connected interfaces on the Layer device are configured with the first usable IP address on their respective networks. (b) Assume the source and destination devices are PC’s and show their IP address on your diagram. (c) Show the MAC address of all devices show in your diagram.
