As part of my last vLecture, I said that I would send configs for the Repeater using a different bridge-group than BG 1, WGB using the workgroup-bridge client-vlan x command, and WGB connecting to a non-native VLAN. Note the use of the "bridge 20 protocol ieee" on the WGB, as well as the "spanning-tree bpdufilter enable" command on the switch attaced to the WGB. The WGB using the client-vlan command would not function without them. And, the WGB connected to the non-native VLAN requires that the "bridge 20 protocol ieee" command be applied to the root AP. Otherwise, the corresponding VLAN (whichever VLAN that bridge group is associated with on the Ethernet side) will go into a blocking state due to "self-looped." That means that the switchport sees the same BPDU that it sent for the VLAN being received on the same port. Hope these help clear up some confusion.
