I think it is a bad idea to bridge between vlans. Since cisco switches running PVST+, the two STP instance will be merged. STP is troublesome.
How about this configuration? (sorry I can't test it right now)
interface FastEthernet0/0
no ip address
duplex auto
speed auto
!
interface FastEthernet0/0.10
encapsulation isl 10
ip address 10.2.1.1 255.255.255.0
no ip redirects
bridge-group 1
bridge-group 1 spanning-disabled
!
interface FastEthernet0/0.20
encapsulation isl 20
no ip redirects
bridge-group 1
bridge-group 1 spanning-disabled
!
interface FastEthernet0/0.30
encapsulation isl 30
no ip redirects
bridge-group 1
interface BVI1
ip address 10.1.1.1 255.255.255.0
( bridge 1 protocol ieee REMOVED!#)
bridge 1 route ip
