In this way, no loop occurs and the communication between the devices in a
VLAN works as well.
10.1.2.1 How to Partition MSTP
regions
According to above description, MSTP regions should be partitioned rationally
and the switches in a MSTP region should be configured similarly for the MSTP
protocol to work properly.
The MST configuration information contains:
z MST region name (name): A string of up to 32 bytes identifying the MSTP
region.
z MST revision number: A revision number of 16 bits identifying the MSTP
region.
z MST instance-vlan table: Each device can create up to 64 instances with
IDs ranging from 1 to 64). Instance 0 always exists, so the system totally
supports 65 instances. You can allocate 1 to 4094 VLANs for different
instances (0 to 64) as needed, and the unallocated VLANs belong to
instance 0 by default. In this way, each MSTI (MST instance) is a VLAN
group and executes the spanning tree algorithm within the MSTI according
to the MSTI information of the BPDU without the effect of the CIST and
other MSTIs.
You can use the spanning-tree mst configuration command in the global
configuration mode to enter the MST configuration mode and configure above
information.
