To implement GVRP in a network, first add the host devices to the required

from joining restricted VLANs.
VLANs (using the o
VLANs can be propagated onto the network. For both the edge switches attached
directly to these hosts, and core switches in the network, enable GVRP on the
links between these devices. You should also determine security boundaries i
the network and disable GVRP on the boundary ports to prevent advertisem
from being propagated, or forbid those ports
Note: If you have host devices that do not support GVRP, you should configure
static or untagged VLANs for the switch ports connected to these devices (as
described in “Adding Static Members to VLANs (VLAN Index)” on page 3-108).
But you can still enable GVRP on these edge switches, as well as on the core
switches in the network.
Forwarding Tagged/Untagged Frames
If you want to create a small port-based VLAN for devices attached directly to a
single switch, you can assign ports to the same untagged VLAN. However, to
participate in a VLAN group that crosses several switches, you should create a
VLAN for that group and enable tagging on all ports.
Ports can be assigned to multiple tagged or untagged VLANs. Each port on the
switch is therefore capable of passing tagged or untagged frames. When
forwarding a frame from this switch along a path that contains any VLAN-aware
devices, the switch should include VLAN tags. When forwarding a frame from this
switch along a path that does not contain any VLAN-aware devices (i
destination host), the switch must first strip off the VLAN tag before for
ncluding the
tag. However, when this switch receives an
frame. When the switch receives a tagged frame, it will pass this frame onto the
VLAN(s) indicated by the frame
untagged frame from a VLAN-unaware device, it first decides where to forward
the frame, and then inserts a VLAN tag reflecting the ingress port’s default VID.
