Configuration Example for MSTP
MSTP, backwards-compatible with STP and RSTP, can map VLANs to instances to
implement load-balancing, thus providing a more flexible method in network management.
Here we take the MSTP configuration as an example.
5.1 Network Requirements
As shown in figure 5-1, the network consists of three switches. Traffic in VLAN 101-VLAN
106 is transmitted in this network. The link speed between the switches is 100Mb/s (the
default path cost of the port is 200000).
It is required that traffic in VLAN 101 - VLAN 103 and traffic in VLAN 104 - VLAN 106 should
be transmitted along different paths.

5.2 Configuration Scheme
To meet this requirement, you are suggested to configure MSTP function on the switches.
Map the VLANs to different instances to ensure traffic can be transmitted along the
respective instance.
Here we configure two instances to meet the requirement, as is shown below:
