How to configure Multiple Spanning Tree (MSTP) on Ruijie Switch?

1. Network requirements

There are 4 vlans on the Intranet. The root bridge of vlan10 and 20 is on core switch A, and the root bridge of vlan30 and vlan40 is on core switch B

2. Topology

3. Configure tips

Enable the spanning tree function first

Create different instances

Configure the priority for the instance

4. Configure steps

Core switch A：

Ruijie>enable

Ruijie#configure terminal

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

Ruijie(config-vlan)#exit

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

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

Ruijie(config-mst)# instance 1 vlan 10, 20 //vlan 10 and 20 use instance1

Ruijie(config-mst)# instance 2 vlan 30, 40 //vlan 30 and 40 use instance2

Ruijie(config-mst)#exit

Ruijie(config)#spanning-tree mst 1 priority 4096 // instance 1 priority is 4096. The smaller, the higher priority is selected to be root. 32768 by default

Ruijie(config)#interface gigabitEthernet 0/1

Ruijie(config-if-GigabitEthernet 0/1)#switchport mode trunk

Ruijie(config)#interface gigabitEthernet 0/2

Ruijie(config-if-GigabitEthernet 0/2)#switchport mode trunk

Ruijie(config)#end

Ruijie#write

Core switch B：

Ruijie>enable

Ruijie#configure terminal

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

Ruijie(config-vlan)#exit

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

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

Ruijie(config-mst)# instance 1 vlan 10, 20          //vlan 10 and 20 use instance1

Ruijie(config-mst)# instance 2 vlan 30, 40          //vlan 30 and 40 use instance2

Ruijie(config-mst)#exi

Ruijie(config)#spanning-tree mst 2 priority 4096 // instance 2 priority is 4096. The smaller, the higher priority  is selected to be root. 32768 by default.

Ruijie(config)#interface gigabitEthernet 0/1

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

Ruijie(config)#interface gigabitEthernet 0/2

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

Ruijie(config)#end

Ruijie#write

Access switch：

Ruijie>enable

Ruijie#configure terminal

Ruijie(config)#vlan range 10,20,30,40 //create vlan 10, 20, 30 and 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 gigabitEthernet 0/1

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

Ruijie(config)#interface gigabitEthernet 0/2

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

Ruijie(config)#end

Ruijie#write

5. Verification

Ruijie#show spanning-tree summary

Ruijie#show spanning-tree mst 1
