M4100 Series Managed Switch
13. Click the ADD button.
In this example, assume that Switch 1 has become the root bridge for MST instance 1, and
Switch 2 has become the root bridge for MST instance 2. Switch 3 has hosts in the Sales
department (ports 1/0/1, 1/0/2, and 1/0/3) and in the HR department (ports 1/0/4 and 1/0/5).
Switches 1 and 2 also use hosts in the Sales and Human Resources departments. The hosts
connected from Switch 2 use VLAN 500, MST instance 2 to communicate with the hosts on
Switch 3 directly. Likewise, hosts of Switch 1 use VLAN 300, MST instance 1 to communicate
with the hosts on Switch 3 directly.
The hosts use different instances of MSTP to effectively use the links across the switch. The
same concept can be extended to other switches and more instances of MSTP.
