should also determine security boundaries in the network and disable
GVRP on the boundary ports to prevent advertisements from being
propagated, or forbid those ports from joining restricted VLANs.
Note: If you have host devices that do not support GVRP, you should

connected to these devices (as described in
“Adding Static
Members to VLANs (VLAN Index)” on page 3-185). But you can
still enable GVRP on these edge switches, as well as on the core
switches in the network.
