These frames will be sent to port 12 which is a member of the same VLAN.
Because the port is set to untagged frames for this VLAN, the tag will be removed
and the frame sent to Device B untagged.

Figure 77. 802.1Q-compliant device (tagging and GVRP) to 802.1Q-compliant device (tagging
and GVRP) configuration
In this configuration, both devices support tagging and GVRP. Both devices are
configured to transmit tagged frames for VLAN 5. GVRP must be enabled for the
switch and for all ports which must participate in GVRP.
When Station A attempts to communicate with Station B, VLAN 5 (that Station A is
a member of) is registered at Port 1 by GVRP. Likewise, Station B registers its
membership with VLAN 5 on Port 12. Note that this VLAN will be dynamic because
the network administrator has not explicitly configured the VLAN on the switch.
Frames arrive at Port 1 from Device A, tagged for VLAN 5. These frames are
forwarded to Port 12. The frames will be transmitted out of Port 12 tagged for
receipt at Station B. Note that all frames in dynamically-created VLANs are
transmitted as tagged.
