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

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
