The purpose of this question:
- Combination of theory and practice : Cisco Packet Tracer is a network simulation software that allows students to deepen their understanding and mastery of theoretical knowledge in practical operations by simulating a real network environment.
- Problem-solving ability : Comprehensive experimental questions can test students' ability to analyze and solve problems. During the experiment, students need to design network topology, configure network equipment, troubleshoot network faults, etc. These are all necessary abilities in actual work.
- Teamwork ability : During the experiment, students need to work together in groups to complete tasks together. This can cultivate students' teamwork and communication skills and lay the foundation for their future teamwork at work.
- Enhance learning interest : Compared with traditional written tests, Cisco Packet Tracer comprehensive experimental questions are more lively and interesting. In the process of solving practical problems, students can understand and master the course content more deeply, thereby increasing their interest in learning.
This question mainly examines router operation, PAT and other knowledge.
Cisco simulation experiment questions:
A school has applied for a public IP address 10.0.0.1. Please design a LAN to complete the following functions:
1. External network users can access the school’s official website by accessing 10.0.0.1. External network users cannot set a gateway on their devices;
2. The school has 2 teaching buildings. Each teaching building contains 200 PCs (the subnet mask address of all PCs is 255.255.255.0, 3 PCs in each building is sufficient). PCs in different teaching buildings can be mutual access.
analyze:
1. There is only one external IP. To meet the needs of the internal network and build an official website, port mapping needs to be used;
2. The subnet mask is limited to 255.255.255.0, and there are 200 PCs in each teaching building. Then a router needs to be used to allow different teaching buildings to access each other.
Answer (the answer is not unique):
1. Draw the topology and set the IP (please note that the gateway of each device and the port IP of the router must be set):
2. Enable rip on Router 2
3. Enable rip on Router 3
4. The server can be accessed from the intranet
5. Enable PAT on router2 (map network segments 30 and 20 to the LAN 192.168.0.0)
6. Configure Router3 PAT
7. Check whether PC5 can ping the external PC (it can ping successfully)
8. The campus official website cannot be accessed from the external network
9. Configure the router to map 192.168.0.1 to 10.0.0.1
10. Access the intranet server from the external network
11. Ping different teaching buildings
