COMP3234 Computer and Communication Networks Problem Set Assignment Three Total 8 points Due date: 17:00 May 2, 2017Answer all questions. Hand-in the assignment via the Moodle System. Question 1 (2 points) (This question is related to ILO2b –“be able to comprehend and explain the principles behind IP technology and IP addressing” and ILO5 –“be able to plan for IP networks and properly assign IP addresses to interfaces in given networks.”)The following figure shows an organization with four subnets. Assume you are the network administrator of this organization. You are going to (a)(1) assign IP addresses to the interfaces of routers R0, R1, & R2 and hosts H0, H1, H2, & H3, (b)(0.4) label each subnet with the corresponding network address/mask, and (c)(0.6) construct the forwarding table for the routers R0, R1, & R2, with following constraints: 1.The expected number of hosts in each subnet is: a.Subnet A: 50 b.Subnet B: 200
c.Subnet C: 200 d.Subnet D: 500 2.The organization is allocated with the network address: 184.108.40.206/21. 3.You are expected to use the least amount of routing entries to represent all the subnets of this site in each forwarding table. 4.For each interface, please show its IP address. (That is, find a suitable IP address within the subnet and allocate that to the interface.) 5.Present the routing table with the following information: Destination address/mask, Nexthop, Interface.where Nexthop gives the target IP address of the nexthop router along the path to the destination; if the destination network is the ultimate destination of the packet, leave Nexthop field as empty; Interface gives the network interface of the router that leads to the nexthop router or the ultimate destination. 7.
