Question 1:

The following is a dump of a TCP header in hexadecimal format:

00CD0018 00000EF1 00000D5D 502200D1 01BF0010

Please answer the following two parts of questions:

Part I

1.1 What is the source port number?

1.2 What is the destination port number?

1.3 What is the sequence number?

1.4 What is the acknowledgment number?

1.5 What is the length of the header?

1.6 Which control bits are set and what do they represent?

1.7 What is the window size?

Part II

1.8 What does the last four digits '0010' of the above dump represent? What action will the destination node take when it receives this packet?

Question 2:

Based on the output from the "show cdp neighbours" command please draw the topology.

Show connections between devices and label the interfaces.

Question 3:

An organization is assigned the network number 172.17.0.0/16, and it must create a set of subnets that supports variable amount of hosts on each subnet. The topology is shown as following figure.

Please use VLSM to design and answer the following questions:

3.1 Define subnet masks (or extended prefix length) for the LANs in this organization

3.2 Write the usable IP range for each Subnet.

3.3 Write explicitly IP address of the host number 68 on the LAN5 explicitly in binary and decimal notation.

3.4 What is the broadcast address for the LAN4?

3.5 Setup and configure the network you designed above using the Packet Tracer router simulator.

a) with RIP v1

b) with RIPv2

Show the routing table for Router 1 after the network is fully converged. Your table should include the route, routing protocol route learned from/or directly connected interface, next hop router address, and metric (bandwidth measured in kbps for metric if appropriate) that are used.

c) Explain why there is no successful connectivity between different subnets when using

RIPv1

3.6 By using RIPv2 protocol, set up one PC in LAN1 and another PC in LAN6. Test the connectivity between them. Based on your observation please give an explanation of the ping process from PC in LAN1 to PC in LAN6 and the routing table lookup progress on R1.
