11. Create a second MST instance with the following settings

• MST ID: 2

• Priority: 49152

• VLAN ID: 500

12. Click the Add button.

In this example, assume that Switch 1 has become the Root bridge for the 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 include 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
