You do not have to specify an IP address for the bridge.

In my case:

mainbr0   Link encap:Ethernet  HWaddr <mac>
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:7328933 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6992 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:481076877 (458.7 MiB)  TX bytes:629184 (614.4 KiB)

tap0      Link encap:Ethernet  HWaddr <mac>
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:139390 errors:0 dropped:0 overruns:0 frame:0
          TX packets:7460821 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:500

# brctl show
bridge name	bridge id		STP enabled	interfaces
mainbr0		8000.<mac>      	no		tap0
							eth0

eth0 is the interface connected to the physical LAN. mainbr0 ties the
VM's tap to eth0.
