Yeslab October July 12, instructor Chen ccna + ccnp real machine rack Practical Course Ccna is an entry-level course in the network industry. In order to give students a good understanding of the network, yeslab provides the real Equipment Rack. The students build the topology and complete the configuration to create a real network for the students, in short, as long as the students want to learn, yeslab is not stingy The

Lab requirements: The topology is simulated based on the typical C3550-Headquarters-branch structure. The core route of the headquarters is C3550. The Extranet network uses the OSPF protocol and the Intranet is deployed through the VTP protocol to achieve network-wide interconnection.1, the headquarters core switch C3550-1 to create VLAN10/20/30/40, of which VLAN40 only for device management, do not port access, VLAN division.2, The C3550-1 is VTP Ser
