Figure 7-1 Example of VLAN Propagation via GVRP
Configuring a VLAN on an 802.1Q switch creates a static VLAN entry. The entry will always
remain registered and will not time out. However, dynamic entries will time-out and their
registrations will be removed from the member list if the end station A is removed. This ensures
that, if switches are disconnected or if end stations are removed, the registered information remains
accurate.
The end result is that the port egress list of a port is updated with information about VLANs that
reside on that port, even if the actual station on the VLAN is several hops away.
