Figure 2-17 Networking with multiple spanning trees instances in MST region

Apply MSTP to the network as shown in Figure 2-17. After calculation, there are two
spanning trees generated at last (two MST instances):


In this case, all VLANs can communicate internally, different VLAN packets are forwarded in
different paths to share loading.

2.7.2 Preparation for configuration

Scenario
In a big LAN or residential region aggregation, the aggregation devices make up a ring for
link backup, avoiding loop and realizing load balancing. MSTP can select different and
unique forwarding paths for each one or a group of VLANs.
Prerequisite
N/A

2.7.3 Default configurations of MSTP

Default configurations of MSTP are as below.
MSTI 1 takes B as the root switch, forwarding packet of VLAN 100.
MSTI 2 takes F as the root switch, forwarding packet of VLAN 200.
