How to configure GVRP?
Description:
In this scenario, PCs belonging to different divisions within a single
corporation cannot communicate with each other. Also, we leave some ports of
switches for GVRP-aware PCs and others for VLAN-unaware PCs. Therefore
the network administrator can manage and configure VLAN smartly based on
what are the different devices and the requirements. For switches on floor 1
and 2, PC that is connected to port 3 joins VLAN 10 statically; PC that is
connected to port 4 joins VLAN 20 statically; and PCs that are connected to
port 1&2 can join VLAN 10/20/30 as determined by its configuration on
GVRP-aware NIC dynamically. For switch in the basement, PC that is
connected to port 1 joins VLAN 30 while the PC that is connected to port 3 can
join VLAN10/20/30 dynamically. Please Note that all the clients connected to
the switches in this scenario should be located in the same subnet (in this
example, the subnet is 192.168.1.0/24)
