- A router running Classless Interdomain Routing (CIDR) has the following entries in its routing table: Address/mask Next hop 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Router 2 Default Router 3 How does a CIDR router work to route the packets it received? For each of the following IP addresses, what will the router do if a packet with that address arrives? (a) 135.46.63.10 (b) 135.46.58.16 (c) 135.46.52.2 (d) 192.53.40.7 (e) 192.53.56.7Using packet tracer, implement a network that has the following components: 1- At least five routers 2- At least 7 subnets 3- At least 12 PCs 4- At least 4 switches 5- Use RIP routing protocol To assign IP addresses of the routers and PCs, use the IP address from your ID as follows Assume your id is 118zyxw, Consider the numbers z, y, x and w as deciemal You have the subnet 118.0.0.0/24 If your ID is 1181234 then the IP is 118.0.0.0/24 Use this subnet to get at least 7 subnets.There is a routing table in the figure on a router. If packets with the following destination IP addresses arrive at the router, where are they routed? a) 198.52.61.10b) 198.53.40.201c) 198.52.60.89d) 198.52.63.113 Show your work and reasoning for each option.
- Assume that you have two computers and a router (default gateway) that have the following TCP/IP configuration and that Computer A wants to send data to Computer E. Match the addresses that will be used in the IP packet and the ethernet frame sent from Computer A. Computer A IP address: 178.23.43.12 Netmask: 255.255.0.0 Default gateway address: 178.23.17.1 MAC Address: 34:2A:C6:C6:55:C3 Computer E IP address: 178.23.54.23 Netmask: 255.255.0.0 Default gateway address: 178.23.10.1 MAC Address: 34:2A:C6:76:3E:12 Default Gateway MAC Address: 65:D3:C9:11:C5:99 Items to Match: IP packet Source IP address: IP packet Destination IP address: Ethernet frame Source MAC address Ethernet frame Destination MAC address Possible Values: 178.23.17.1 178.23.10.1 178.23.43.12 178.23.54.23 34:2A:C6:C6:55:C3 65:D3:C9:11:C5:99 34:2A:C6:76:3E:12A router has the following entries in its routing table: 135.46.56.0/22 Interface 0 135.46.60.0/22 Interface 1 192.53.40.0/23 Interface 2 Default Interface 3 For each of the following IP addresses, what does the router do if a packet with that address arrives? a. 135.46.63.10 b. 135.46.57.14 c. 135.46.52.2 d. 192.53.40.7 e. 192.53.56.7A network configuration of a modem is given as following:LTE interface IP = 77.110.156.22 MASK 255.255.252.0Default GATEWAY = 77.110.156.1Masquerade NAT, and DNS address = 1.1.1.1Local IP setup: 192.168.128.1 MASK 255.255.255.0And, ip route 192.168.128.0 255.255.252.0 192.168.128.254 Devices numbered R1, R2, R4, R5 are routers. PC is a computer.Image of network with interface names such as f1/0 are added. You must use only static IP addreses and static IP routes to configure the network and make PC able to connect (ping) to Modem.
- . Assume: Your laptop's Ethernet address is 0a:0b:0c:0d:0e:0f, DHCP server address is 131.111.7.3, your IPv4 address will be 131.111.7.121, the gateway's IP address is 131.111.7.1, and Ethernet address is 00:01:02:03:04:05, the network subnet mask is 255.255.255.0.Write the series of protocol/packet exchanges that occur on the wired Ethernet link, up until you can send a single packet to 128.232.0.20. You do not need to describe packets after this packet has left the link. Include ARP and DHCPA network system has 5 protocol layers. Applications generate messages of length M bytes. At each of the layers, an h-byte header is added. What fraction of the network bandwidth is filled with headers? a. 5h/(5h+M) b. M/(5h+M) c. M/(4h+M) d. 4h/(4h+M)4. A router receives a packet with destination address 196.77.26.206 Show how it finds the network and the subnetwork address to route the packet. Assume the number of subnetworks required is four. Please solve it using the keyboard, not using the hand, and quickly, and I hope that the solution is correct.
- Assume that there are four routers (R1, R2, R3, and R4) and four hosts (H1, H2, H3, and H4) in a network (N1). H1 sends an email to an instructor H3 at SEU.EDU.SA. (192.168.1.1) and the router path is R1, R3, R2, and R4, but the H3 host find a parameter problem and dropped the packet. Explain how ICMP protocol can be used as a debugging tool and draw a diagram to illustrates the traceroute process for this scenario? PART 2 || Characteristics The Transport-layer Protocol It is a simple connectionless protocol with neither flow nor error control. The size of the send window must be less than 2m; the size of the receive window is always 1. Each time a single packet is lost or corrupted, the sender resends all outstanding packets, even though some of these packets may have been received safe and sound but out of order. Both the sender and the receiver use a sliding window of size 1. The sender sends one packet at a time and waits for an acknowledgment…Suppose a user from Taman Jatt Kata Kinabalu is working from a machine at home with IP address 10. 0. 0.10 on a local network attached to a router connected to the Internet The user requests a web page through a Web browser. Show using illustration when and why each of the following aspects of networking are involved. Be as precise as possible. i ARP ii NAT iii DNS iv UDP v TCP.For example, let say that your Network 1 needs 30 hosts and you are in a class C network, you would start with 192.168.0.1 till 192.168.0.32 because the closest you can get to 30 that is more is 32 (2exp5) so my begin address would be 192.168.0.1, end address would be 192.168.0.32 (not 192.168.0.30 because we only need 30 hosts) and subnet mask would be 255.255.255.224. The next range will start at 192.168.0.33!!! Use the example to answer: We are going to use the private range for a class A network. What is its standard subnet mask? A) Network 1 needs 250 hosts B) Network 2 needs 230 hosts
