A comprehensive case of Cisco inter-VLAN routing and HSRP topology Description: www.2cto.com 1. R3 and R4 simulate the customer's pc, which belong to vlan10 and vlan20 respectively. Vlan10 and vlan20 represent different departments in reality. 2. SW1 is a layer-3 switch, and SW2 is a layer-2 switch. 3. R5 simulates the internet. R5 has a lo0: 5.5.5.5/24 loop port.

During hard disk data sorting, we found the original dtp vlan jump experiment video, which includes DTP protocol data packets, test tools, videos, and lazy. The following are the steps. Download the video and watch it. It was very casual. At that time, I kept it for reference. Implementation of VLAN jump attacks I don't talk much about it. I only find such a term on the Internet. No one has told me the
