To enable dynamic VLAN information register and update among switches, GVRP
protocol is to be configured in the switch. Configure GVRP in Switch A, B and C, enable
Switch B to learn VLAN100 dynamically so that the two workstation connected to
VLAN100 in Switch A and C can communicate with each other through Switch B without
static VLAN100 entries.
