Title: How to configure stp on Ruijie Switch?
1. Networking topology:

2. Configuration points:

1)Enable the spanning tree function

2)Create different instances

3)Configure the priority for the instance

3. Configuration procedure:

Note: Before configuration, you are advised to run the Ruijie#show interface status command to check the interface name. The common interface names are FastEthernet (Gigabit), GigabitEthernet(Gigabit), and TenGigabitEthernet(Gigabit). The following configurations use Gigabit interfaces as an example.

Core switch A configuration:

Ruijie>enable //Enter privileged mode

Ruijie#configure terminal //Enter global configuration mode

Ruijie(config)#vlan 10 //create vlan 10, 20, 30 and 40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree //enable spanning tree, default mode is mst

Ruijie(config)#spanning-tree mst configuration //configure mst

Ruijie(config-mst)# instance 1 vlan 10, 20 //vlan 10 and 20 use instance (instance) 1

Ruijie(config-mst)# instance 2 vlan 30, 40 //vlan 30 and 40 use instance (instance) 2

Ruijie(config-mst)#spanning-tree mst 1 priority 4096 //instance (instance) 1 has a priority of 4096, the smaller the priority the higher the priority, the default priority is 32768

Ruijie(config-mst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk

Core switch B configuration:

Ruijie>enable //enter privileged mode

Ruijie#configure terminal //Enter global configuration mode

Ruijie(config)#vlan 10 //create vlan 10, 20, 30 and 40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree

Ruijie(config)#spanning-tree mst configuration

Ruijie(config-mst)# instance 1 vlan 10, 20

Ruijie(config-mst)# instance 2 vlan 30, 40

Ruijie(config-mst)# spanning-tree mst 2 priority 4096

Ruijie(configmst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk //configure the first 100-gigabit interface of the switch as trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk //Configure the second 100-gigabit interface of the switch as trunk

Accessing the switch configuration:

Ruijie>enable

Ruijie#configure terminal

Ruijie(config)#vlan 10 //create vlan 10, 20, 30 and 40

Ruijie(config-vlan)#vlan 20

Ruijie(config-vlan)#vlan 30

Ruijie(config-vlan)#vlan 40

Ruijie(config-vlan)#exit

Ruijie(config)#spanning-tree

Ruijie(config)#spanning-tree mst configuration

Ruijie(config-mst)# instance 1 vlan 10, 20

Ruijie(config-mst)# instance 2 vlan 30, 40

Ruijie(config-mst)#exit

Ruijie(config)#interface FastEthernet 0/1

Ruijie(config-if-FastEthernet 0/1)#switch mode trunk

Ruijie(config)#interface FastEthernet 0/2

Ruijie(config-if-FastEthernet 0/2)#switch mode trunk

Save the configuration

Ruijie(config)#end

Ruijie#write //Confirm the correct configuration and save the configuration

4. Configuration verification:

1）Ruijie#show spanning-tree summary
