Question
2 This question is about Networks The following diagram shows a set of interconnected networks. The four networks (networks 1-4) are shown as labelled ellipses and the machines (A-K) con- nected to the networks represented as letters. Some machines (such às c, ánd E) are connected to multiple networks and are set to forward packets between the two networks. For the purposes of this guestions, machines will be addressed using the format 1.A where the number refers to the network the machine is connected and the let- ter identifies the machine. Machines connected to multiple networks can be ad- dressed usiņng multiple addresses - for example, machine c can be referred to as 1.cor 2.c depending on which network it is talking to. G Network 3 Network 1 -C Network 2 -F B D E Network 4 -K The network is configured to use next-hop routing. In the following questions, you are required to give the address of the next-hop where a machine should send a packet, if it is not on the same (local) network as the machine in question. If the machinies are on the same netwòrk then you can just say the packet would be sent locally. (a) Where should machine D send packets destined for machine H? (b) Where should machine D send packets destined for machine B? (c) Complete, by inspection, the following routing table for machine K (where 1.* means all máchines on network 1 etc.).
