2. RSTP Configuration Example

In this configuration example, we will accomplish the following:

Configure the bridge priority as shown in Figure 3. This will result in 8600-1 becoming the RSTP
Root Bridge. If 8600-1 should fail, then 8600-2 should become the Root Bridge based on priority
settings.

Two VLANs will be configured, a management VLAN (VLAN 200) and a end user VLAN (VLAN
1000)

For the management VLAN 200, we will configure a management IP address as shown in the
diagram above – for this example, no routes are configured for the management as it is a simple
Layer 2 network

As an option, we can set the RSTP port priority on 8600-1 to influence the link taken between
8600-1 and 8600-2. The default port priority simply has to be changed to a lower value on 8600-1
from the default setting of 128

The port priority setting is configured in increments of 16 from 0 to 240
After all the switches have been configured using the above settings, traffic should flow as that shown in
the following diagram.
