How to configure stp on Ruijie Switch?
1. Networking topology:data/attachment/forum/202308/15/130915szslkkx4ck9ldzu4.png
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
