Question 1
USQ College has a campus in Toowoomba with 2 buildings. The computers in each building are linked to a switch and a router as shown. The network in each building is a (sub)network of its own. The diagram includes only 2 PCs for clarity. The 2 buildings are then linked, using serial cables, to another router R0 as shown in the logical network diagram below:
Address scheme for the campus:
• All devices have both IPv4 and IPv6 addresses assigned.
• Building 1: all devices have IPv4 and IPv6 addresses in 200.200.1.0/24 and 2001:DB8:ACAD:1::/64
• Building 2: all devices have IPv4 and IPv6 addresses in 200.200.2.0/24 and 2001:DB8:ACAD:2::/64
• R0 has IPv4 and IPv6 addresses in 169.254.1.0/24, 169.254.2.0/24, 2001:DB8:FADE:1::/64 and 2001:DB8:FADE:2::/64
• R1 has IPv4 and IPv6 addresses in 169.254.1.0/24 and 2001:DB8:FADE:1::/64
• R2 has IPv4 and IPv6 addresses in 169.254.2.0/24 and 2001:DB8:FADE:2::/64 Implement the network using Packet Tracer. You must use router 2911, switch 2960 and
a) Static routes are used. Save your work as Q1_STATIC.pkt.
b) RIP version 2 and RIPng are used as the routing protocols. Save your work as Q1_RIP.pkt.
c) EIGRP is used as the routing protocols. Save your work as Q1_EIGRP.pkt.
d) OSPF V2 and OSPF v3 for single area are used as the routing protocols. Save your work as Q1_OSPF.pkt.
e) Explain the differences between next-hop static route, directly connected static route and a fully specified static route. Which one is better? Why? Put your answer in answer.txt.
f) What is the administrative distance for a directly connected staic route? Put your answer in answer.txt.
All PCs should be able to talk to each other using IPv4 and IPv6.
After 2 years of trial, USQ College decided to use the standard OSPF protocol for muti-area. Each building will be one area. The connecting router R0 will be the only device in the backbone area.
The logical network diagram of USQ College is shown below:
Address scheme for USQ College is the same as in Question 1.
Implement the network using Packet Tracer. You must use router 2911, switch 2960 and OSPF as the routing protocol. Save your work as Q2_OSPF_multi.pkt.
All PCs should be able to talk to each other using IPv4 and IPv6.
Question 3:
Given the following network topology:
All switches will be using fastethernet ports (bandwidth 100,000 Kbit) only.
The partial outputs of show interface command for each router are shown below:
R1#show int g0/0
GigabitEthernet0/0 is up, line protocol is up (connected) Internet address is 200.200.1.254/24
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
R1#show int s0/0/0
Serial0/0/0 is up, line protocol is up (connected) Internet address is 200.200.2.1/24
MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec,
R2#show int s0/0/1
Serial0/0/1 is up, line protocol is up (connected) Internet address is 200.200.2.2/24
MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec,
R2#show int g0/0
GigabitEthernet0/0 is up, line protocol is up (connected) Internet address is 200.200.3.2/24
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
R3#show int g0/0
GigabitEthernet0/0 is up, line protocol is up (connected) Internet address is 200.200.4.254/24
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
R3#show int g0/1
GigabitEthernet0/1 is up, line protocol is up (connected) Internet address is 200.200.3.3/24
MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec,
a) In R1, the G0/0 interface is shown as having bandwidth 100,000 Kbit whereas in R2, G0/0 interface is shown as having bandwidth 1,000,000 Kbit. Explain why.
b) Calculate the EIGRP metric from R1 to network where PC2 is located. Explain and show how you derive at the values used in the calculation. Show detailed steps in arriving your answer.
c) Explain how the feasible condition can guararantee no loops will be created by the feasible successor. Put all your answers in answer.txt.
Question 4:
Download Q4.pkt. The network topology for Q4.pkt is shown below:
a) Explain under what circumstances can R1 became DR and R2 became BDR. Put your answer in answer.txt.
b) Make R3 as the DR and R4 as the BDR by changing the OSPF interface priority. Save your file as Q4ans.pkt.
Question 5:
Download Q5.pkt. The network topology of Q5.pkt is shown below:
a) Implement extended ACL for IPv4 to block LAN 11 and LAN 12 to access LAN 22 for web browsing at port 80. All other traffic including Ping should still be allowed
b) Implement ACL for IPv6 to block all traffic from LAN 11 and LAN 12 to access LAN 22. In both cases,
• LAN 21 can access LAN 22 without any restriction;
• LAN 11, LAN 12, and LAN 21 can freely access each other.
Your implementation should follow the "Three Ps" and guidelines for ACL placement. Save your answer as Q5ans.pkt.
Question 6:
USQ College has 4 campuses
1. Toowoomba;
2. Fraser Coast;
3. Springfield
4. Ipswich.
And each campus has more than 20 buildings, 200 subnets, and over 1,000 users. The routers used in USQ College are not supplied by Cisco.
RIP, EIGRP, OSPF are some of the common routing protocols used in Cisco routers. Which one would you use if you are the network administrator for USQ College?
Present your arguments:
• In less than two pages.
• Use dot point form and complete sentences.
• All reasons should be referenced.
• Draw your conclusion.
(e.g.
"Which one is better: Banana or Orange?"
Banana is better:
Banana has a cheaper price, around $2 per kg [Peter, 2001].
It is easy to peel [Paul, 2012] and would not make a mess during consumption [Pearson, 2010].
...
Orange is better:
Orange is available all year round [Mary, 1918].
It stay fresh much longer than Banana [Alice, 2015].
...
My conclusion is that Banana is better than orange because ... // a summary of reasons listed above that support your choice.
