MSTP Configuration on Huawei eNSP

MSTP is an enchanced STP version. With MSTP, both multiple STP instances can be used and one more VLANs can be added to these instances. In this lesson, we will configure MSTP on Huawei switches with Huawei eNSP.

For our Huawei MSTP Configuration Example, we will use the below switched topology.

Now, let’s go to the MSTP Configuration Steps on Huawei eNSP.

Configuring VLANs, Trunks and Allowed VLANs on Trunks

We will configure the switch interfaces as trunk and then we will add the allowed vlans on this trunk interfaces. We will create VLANs from 2 to 4094. The default VLAN, VLAN 1 is already exist. We will configure this on all the switches.

< Huawei-Switch-1> system-view
[Huawei-Switch-1] interface gigabitethernet0/0/1
[Huawei-Switch-1-GigabitEthernet0/0/1] port link-type trunk
[Huawei-Switch-1-GigabitEthernet0/0/1] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-1-GigabitEthernet0/0/1] quit
[Huawei-Switch-1] interface gigabitethernet0/0/2
[Huawei-Switch-1-GigabitEthernet0/0/2] port link-type trunk
[Huawei-Switch-1-GigabitEthernet0/0/2] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-1-GigabitEthernet0/0/2] quit

< Huawei-Switch-2> system-view
[Huawei-Switch-2] interface gigabitethernet0/0/1
[Huawei-Switch-2-GigabitEthernet0/0/1] port link-type trunk
[Huawei-Switch-2-GigabitEthernet0/0/1] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-2-GigabitEthernet0/0/1] quit
[Huawei-Switch-2] interface gigabitethernet0/0/2
[Huawei-Switch-2-GigabitEthernet0/0/2] port link-type trunk
[Huawei-Switch-2-GigabitEthernet0/0/2] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-2-GigabitEthernet0/0/2] quit

< Huawei-Switch-3> system-view
[Huawei-Switch-3] interface gigabitethernet0/0/1
[Huawei-Switch-3-GigabitEthernet0/0/1] port link-type trunk
[Huawei-Switch-3-GigabitEthernet0/0/1] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-3-GigabitEthernet0/0/1] quit
[Huawei-Switch-3] interface gigabitethernet0/0/2
[Huawei-Switch-3-GigabitEthernet0/0/2] port link-type trunk
[Huawei-Switch-3-GigabitEthernet0/0/2] port trunk allow-pass vlan 1 to 4094
[Huawei-Switch-3-GigabitEthernet0/0/2] quit

MST Mode Configuration

To set STP mode as MSTP, we will use “stp  mode mstp” command on each switch.

[Huawei-Switch-1] stp mode mstp

[Huawei-Switch-2] stp mode mstp

[Huawei-Switch-3] stp mode mstp

MST Region Configuration

We will start to configure MSTP Region with “stp region-configuration” command. After that, we will configure MSTP Region name. Then, we will set the instance-vlan mappings. All the VLANs are mapped to MSTI 0 by default. We will configure this new mapping manually.

Lastly, we will activate the MST Region configuration with “activate region-configuration” command.

[Huawei-Switch-1] stp region-configuration
[Huawei-Switch-1-mst-region] region-name OurRegion
[Huawei-Switch-1-mst-region] instance 1 vlan 1 to 3 
[Huawei-Switch-1-mst-region] instance 2 vlan 4 to 6 
[Huawei-Switch-1-mst-region] active region-configuration  
[Huawei-Switch-1-mst-region] quit

[Huawei-Switch-2] stp region-configuration
[Huawei-Switch-2-mst-region] region-name OurRegion
[Huawei-Switch-2-mst-region] instance 1 vlan 1 to 3 
[Huawei-Switch-2-mst-region] instance 2 vlan 4 to 6 
[Huawei-Switch-2-mst-region] active region-configuration  
[Huawei-Switch-2-mst-region] quit
