A10E/A28E/A28F Configuration Guide
Figure 7-13 Networking of multiple spanning trees instances in MST domain
Applying MSTP in the network as Figure 3-10 above, after calculation, there are two
spanning trees generated at last (two MST instances):
MSTI1 takes Switch B as the root switch, forwarding packet of VLAN100.
MSTI2 takes Switch F as the root switch, forwarding packet of VLAN200.
In this way, all VLANs can communicate at internal, different VLAN packets are forwarded
in different paths to share loading.
7.5.2 Preparation for configuration
Scenario
In big LAN or residential region aggregation, the aggregation devices will make up a ring for
link backup, at the same time avoid loop and realize service load sharing. MSTP can select
different and unique forwarding path for each one or a group of VLAN.
Prerequisite
Configure interface physical parameters to make it Up before configuring MSTP.
7.5.3 Default configurations of MSTP
The default configuration of MSTP is as below.
