Objective:

Share with me today a Cisco integrated small experiment, difficulty CCNA level. It mainly involves the following knowledge points: VLAN, DHCP, STP (spanning-tree) +HRSP (standby), OSPF, NAT, ACL. The GNS3 simulator is used in the experiment. The experiment is as follows:

Experimental Purpose:

The ultimate experiment was designed to allow the PC to access the R2 loopback interface (the Internet is being emulated here). Specific implementation details, according to the configuration to determine their own. In doubt, please leave a comment below, and welcome to discuss together.
