q no 5: In the above network diagram, IP and MAC addresses are given for network nodes. Suppose Host1 (Shahid) sends a datagram to Host2 (Khalid). What IP and MAC addresses (source and destination) will be written in IP and Data link layer headers respectively, for the following intermediate points from Host1 to Host2? Host1 to Router1 (R1) Router1 to Router2 (R2) Router2 to Host2
Consider the following diagram: A,B,C and D are subnets, R1, R2, and R3 are routers. Default signifies theentire rest of the internet. All 4 subnets each contain the same number of hosts.Consider the following routing table at R3: CIDR Mask Link 0.0.0.0/0 L4 128.4.6.0/24 L3 128.4.8.0/24 L5 1. If 128.4.6.0 is in A, what is the routing table at R1? 2. The ISP that owns all these networks is short on IP addresses, so theyuse a NAT router for R2. How many public IP addresses will C andD use together assuming they use as many private 10.X IP addresses asthey can? How many total public IP addresses will be used by the entirenetwork? Why doesn’t the ISP care about how many private IP addressesare used? 3. Fix R3’s routing table now that we are using NAT: 4. A node in C is given the IP address 10.0.0.1 and only sends and receivespackets on port 1234. A packet destined for this node reaches R2 witha source of (IP=128.4.6.6, Port=3000) and destination of (IP=128.4.8.0,Port=10000).…

P8. Consider a router that interconnects three subnets: Subnet 1, Subnet 2, and Subnet 3. Suppose all of the interfaces in each of these three subnets are required to have the prefix 223.1.17/24. Also suppose that Subnet 1 is required to support at least 60 interfaces, Subnet 2 is to support at least 90 interfaces, and Subnet 3 is to support at least 12 interfaces. Provide three network addresses (of the form a.b.c.d/x) that satisfy these constraints.

Assign network addresses to each of these six subnets,with the following constraints: All addresses must be allocated from 212.10.8/23; Subnets A, B, and C should have enough addresses to support 120, 240, and 120 interfaces respectively. Of course, subnets D, E, and F should each be able to support two interfaces. For each subnet, the assignment should take the form of a.b.c.d/x or a.b.c.d/x - e.f.g.h/y. ----- Using your answer to the previous part, provide the forwarding tables (using longest prefix matching) for each of the three routers. You may use label R1A to denote the interface on router R1 that is part of subnet A and so on.
