bridging between Vlans on Cat. 8510 MSR

Hi there

I've got a problem with bridging between vlans on a Catalyst 8510 MSR.

Setup:

interface FastEthernet0/0/3.806
description Site A - port 1
encapsulation dot1Q 806
no cdp enable
bridge-group 251
bridge-group 251 spanning-disabled
!
interface FastEthernet0/0/3.807
description Site A - port 2
encapsulation dot1Q 807
no cdp enable
bridge-group 252
!
interface FastEthernet0/0/3.808
description Site B - port 1
encapsulation dot1Q 808
no cdp enable
bridge-group 253
bridge-group 253 spanning-disabled
!
interface FastEthernet0/0/3.809
description Site B - port 2
encapsulation dot1Q 809
no cdp enable
bridge-group 254
bridge-group 254 spanning-disabled


bridge 253 protocol ieee
bridge 253 route ip
bridge 254 protocol ieee
bridge 254 route ip


As you can see, I've got 2 sites with 2 VLANs that I want to bridge
between.

It seems that there are no trafic passing between fa0/0/3.806 and
fa0/0/3.808 even tough they are bridged together. I've tried with "bridge
254 protocol vlan-bridge" but it won't work because I'm prohibited to
enter "bridge-group 254" on the subinterfaces (something with spanning-
tree and vlan-bridge, but I can't find any documentation...)

Please help anyone
