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

PC1 192.168.10.1 255.255.255.0 192.168.10.250 (the gateway is a virtual gateway, which is reflected in part 3)

two。 Configure SW4

Create VLAN 10 20 on SW4

Configure the gi 1 interface as an access link and join VLAN 10

Configure the gi 2 interface as a trunk link to allow all VLAN to pass through

Configure the gi 3 interface as a trunk link to allow all VLAN to pass through

Create a STP on SW4 and name it LLL

Add VLAN 10 to a group with priority set to 4096

Add VLAN 20 to the second group, with priority set to 8192

3. Configure SW5

Create VLAN 10 20 on SW5

The command input error in this picture does not take a screenshot without a molding, just like the configuration of SW2.

Set SW3 as the root bridge
