What do you mean by “tagging the bridge”? Frames can be tagged and untagged, bridges cannot.
The bridge forwards a frame with any VLAN ID that makes it to it; you can configure which VLANs are allowed on which port and whether frames belonging to these VLANs should be tagged on ingress & untagged on egress through that port or left intact.
Please have a look at this post and tell me whether it has helped.
