VLANs and especially STP make things more interesting.

With traditional bridging, you would bridge the three (virtual) 
interfaces together and then bind your server's IP(s) to the bridge 
interface.  I've got a system in service that has an excess of 24 
different VLAN interfaces bridged together, and it's working great.
