1. Configure basic MSTP functions, add devices to MST regions, and create MSTIs.
NOTE
l Each ring can belong to only one region.
l Each CE can join only one ring.
2. Configure multiple MSTP processes, including:
(1) Create multiple MSTP processes and add interfaces to relevant processes.
(2) Configure a share-link.
3. Configure MSTP protection functions, including:
l Configure priorities of MSTP processes and enable root protection.
l Configure share-link protection.
4. Configure the Layer 2 forwarding function on devices.
Data Preparation
To complete the configuration, you need the following data:
l Name of an MST region and names of MSTIs (MSTI 1, MSTI 2, and MSTI 3)
l VLAN IDs (2 to 300)
l IDs of MSTP processes
Procedure
Step 1 Configure basic MSTP functions, add devices to an MST region, and create MSTIs.
1. Configure MST regions and create MSTIs.
# Configure an MST region and create MSTIs on Switch A.
<Quidway> system-view
[Quidway] sysname SwitchA
[SwitchA] stp region-configuration
[SwitchA-mst-region] region-name RG1
[SwitchA-mst-region] instance 1 vlan 2 to 100
[SwitchA-mst-region] instance 2 vlan 101 to 200
[SwitchA-mst-region] instance 3 vlan 201 to 300
[SwitchA-mst-region] active region-configuration
[SwitchA-mst-region] quit
# Configure an MST region and create MSTIs on Switch B.
<Quidway> system-view
[Quidway] sysname SwitchB
[SwitchB] stp region-configuration
[SwitchB-mst-region] region-name RG1
[SwitchB-mst-region] instance 1 vlan 2 to 100
[SwitchB-mst-region] instance 2 vlan 101 to 200
[SwitchB-mst-region] instance 3 vlan 201 to 300
[SwitchB-mst-region] active region-configuration
[SwitchB-mst-region] quit
2. Enable MSTP.
# Configure Switch A.
[SwitchA] stp enable
# Configure Switch B.
[SwitchB] stp enable
Step 2 Configure multiple MSTP processes.
