NETW204 Introduction to Routing with Lab

Week 1 Homework

Switching Concepts

Look at the Ethernet header below. Explain the following fields in the Ethernet header.

(10 points, 2 points for each correct field explained.)

You are the most recently hired network engineer out of a group of 10 network engineers. During a meeting to implement a new switching technology, your manager asks the team to decide on which switching forwarding technique to use—cut-through or store-and-forward. You are required to come up with advantages and disadvantages of using both cut-through and store-and-forward. What would your list entail? Provide support for each item in your list. (10 points)

Explain how each of the following commands below will impact the switched network? Which command is the default command used when setting up port-security on a Cisco switch? (10 points)

Week 2 Homework

VLAN

A network engineer typed the following command on a switch hostname S1 and observed the output below. Explain each entry in the output and the possible source for each MAC address in the MAC Address Table. (10 points)

Explain the significance of each of the following types of VLAN: Data, Management, Native, and Blackhole. Explain where each type of VLAN fits into a LAN network. In addition, what is the default VLAN on a Cisco switch for Data, Management, and Native frames? Justify your answer (10 points)

List the range of Normal VLANs. What VLANs are reserved in that range? List the Extended VLAN range. What, if any, VLANs are reserved in that range? (10 points)

Week 3 Homework

Inter-VLAN Routing

A Given the network diagram below. Enter the commands, including the router prompt, to configure the router, for router-on-a-stick. (10 points)

Given the network diagram below. Enter the commands, including the switch prompt, to configure S1 to forward VLAN traffic. (10 points)

The organization added a new VLAN, VLAN 200, to the network. You are required to implement a solution that provides the best performance to the server segment, VLAN 200. How would you configure the router to ensure that the server segment will not experience bottleneck between the end devices on the server segment and the router? Enter the commands you would use on the router to implement this solution. Justify your answer. (10 points)

Week 4 Homework

Static and Dynamic Routing

A network engineer is troubleshooting a small LAN network with one border router, GW01 that connects to the Internet Service Provider’s (ISP) network. GW01 uses its Serial 0/2/1 interface to connect to the ISP’s router. Everyone on the LAN network lost connectivity to the Internet. Upon troubleshooting the issue, the network engineer notices the following message after typing show ip route. Gateway of last resort required but not set. What do you suggest the network engineer do to rectify this issue? Assume the problem is only on the organization’s LAN side of the network. Provide as much information as possible including specific commands and all required parameters. (10 points)

A Cisco router has learned the following destination prefix 209.175.28.0 /24 from its directly connected network, static routing, and via dynamic routing. List in order of importance the way the router will go about inserting the route in its final routing table assuming everything is now working. What is the Cisco router using to make that decision? Explain when the dynamic routing protocol information will be utilized in the routing table. (10 points)

The show ip interface brief command executed on router1 R1 and R2 generated the following output. What would be the static route commands that you would type on R2 in order to reach R1’s subnets. Provide complete configuration command with destination prefixes and next-hop information or exit interface. Assume R1 is already configured. (10 points)

Week 5 Homework

OSPF

Given the diagram below and OSPF properly configured on routers 1 and 2. The network engineer typed two Cisco IOS commands in the Command Line Interface (CLI) back to back and observed the output below.

Explain how the cost to the 192.168.1.0/24 route was calculated in OSPF. (15 points)

Explain the steps that two routers take to become fully adjacent neighbors in OSPF. (15 Points)

Explain the difference between DR, BDR, and DROTHER. How would you go about changing the BDR to DR assuming all the routers are up and operational (nothing went down)? What would be the impact of such a change on a live or production network? (15 points)

Week 6 Homework

IPv6

Given the following IPv6 address: 2008:0000:05A3:0000:0000:00FB:0C7A:FE29/64. Simply the address to be optimal in IPv6 (rewrite the address to be the shortest possible IPv6 equivalent address). Explain what you did. (10 points)

Given the diagram below. Assume the IPv6 prefix is 2005:007D:4500:000C::/64. Find the IPv6 EUI addresses for computers A and B. Show all your work. Do not just copy and paste the final answer to avoid losing points. (20 Points)

The following IPv6 prefix, 2009:0000:00AF::/48, was assigned to ABC Corporation. You are required to subnet the given network to use a /64 subnet mask. Find the first 15 IPv6 subnets. List the subnets below, one subnet per line. (15 points)
