Configuration Example
3.1 Network Requirements
Department A and Department B of a company are connected using switches. Offices of
one department are distributed on different floors. As shown in Figure 3-1, the network
topology is complicated. Configuration of the same VLAN on different switches is required
so that computers in the same department can communicate with each other.

3.2 Configuration Scheme
To reduce manual configuration and maintenance workload, GVRP can be enabled to
implement dynamic VLAN registration and update on the switches.
When configuring GVRP, please note the following:
■ The two departments are in separate VLANs. To make sure the switches only
dynamically create VLAN of their own department, you need to set the registration
mode for ports on Switch 1 to Switch 4 as Fixed to prevents dynamic registration and
deregistration of VLANs and allow the port to transmit only the static VLAN registration
information.
■ To configure dynamic VLAN creation on other switches, set the registration mode of
the corresponding ports as Normal to allow dynamic registration and deregistration of
VLANs.
