Abstract: According to the experimental teaching characteristic of routing and switching technology,a comprehensive experiment of the campus network was designed.The experiment integrated the knowledge points of VLAN,DHCP,RIP,default routing,ACL and NAT to form the network.After a series of steps such as equipment section,connection and configuration,the simulation of the experiment is completed by using the simulation software,and experimental results are verified.The results show that the experiment realizes the basic requirements of the park network,and promotes the students to master the related technology of building the park network in theory and practice,and also provides a reliable reference for the teachers.
