Application experiment of Huawei equipment STP,VRRP
Lab Topology:
The purpose of the experiment is to use STP,VRRP; to understand the loop and solve it, and to make the whole network interworking.
PC1 and PC3 belong to vlan 10, and PC4 belong to VLAN 20.
Experimental idea: divide the topology diagram into three parts; start with the bottom terminal equipment
Configuration steps: the first part
1. Configure IP subnet mask gateways for PC1 and PC2
