2.5 configure HTTP server and modify index HTML, add ZUCC NetLab and other information, and the screenshot is as follows:

2.6 verify connectivity

Add a simple PDU between PC3 and HTTP Server for verification. The screenshot is as follows:

Use the Web browser of PC4 to access the page of HTTP server. The screenshot is as follows:

4, Harvest feeling:

Through this experiment, I understand the basic configuration method of static routing and the role of routing table, and deepen my understanding of the role of router, which will benefit me a lot in the future theoretical courses.
