1. In TCP/IP, there are 2 main types of Interior Routing Protocols (IRPs) namely distance vector routing protocols, such as RIP, and link state routing protocols, such as OSPF and IS-IS. Write a short report (no more than 750 words) that explains each of the 6 terms in bold and why each is significant in the context of a data network.
2. Compare and contrast the role of areas in the 2 main link state routing protocols, namely OSPF and IS-IS. You should briefly examine the role of virtual links in OSPF. Write your answer in the form of a short report of no more than 750 words.
3. Consider the following case study which depicts a network for the London School of Routing; it comprises a number of routers and PCs. The interior routing protocol for the entire network is to be OSPF and the network manager has decided to partition the network into 4 areas as shown:
You are to develop an addressing scheme and apply the appropriate addresses/subnet masks to the router interfaces and the 2 PCs. You should also specify the configuration of the OSPF areas (paying particular attention to the requirement for a virtual link)
You are not required to use the Packet Tracer tool but you may wish to experiment with it. A Packet Tracer file of the Central London Infrastructure of the London School of Routing is included with this assignment to help you get started. If you do use Packet Tracer you might wish to demonstrate that your combined addressing and routing scheme works by pinging between the 2 PCs in both directions.
Whether you choose to use Packet Tracer or not, write a short report of no more than 1000 words explaining the logic behind your addressing scheme and your configuration of the OSPF routing protocol for the Central London Infrastructure of the London School of Routing.
