Hi
We provide ADSL services for our customers (with PPPOE).
some of our Customers need VPN Service for their clients , for that we used the Cisco 3661 Router with BVI interface to
provide Layer 2 protocol for them.
some of our Customers want to run OSPF over their LAN (that we Provide for them), but our problem is that Multicast
Packets (224.0.0.5 and 224.0.0.6) does not transfer between Customer Routers , this is true about other multicast packets ,
for example CDP.
----------------------
ip cef
vpdn enable
!
vpdn-group 1
accept-dialin
protocol pppoe
virtual-template 2
pppoe limit per-vc 1000
!
bridge irb
interface BVI110
ip address 10.10.10.100 255.255.255.0
!
interface FastEthernet0/0
pppoe enable
interface FastEthernet0/0.916
encapsulation dot1Q 916
no ip route-cache
no ip mroute-cache
bridge-group 110
interface FastEthernet0/0.917
encapsulation dot1Q 917
no ip route-cache
no ip mroute-cache
bridge-group 110
----------------------
Any feedback on this would be greatly appreciated.

I am not sure that I understand clearly your question. I will suggest some answers and if they are not what you need then perhaps you can clarify the question.
You mention using VPN. You can not send multicast like OSPF over normal IPSec VPN. This is because IPSec processes unicast not multicast traffic. If you want to send multicast over IPSec VPN then you need to implement IPSec VPN with GRE tunnels. This will allow multicast to be sent. I have done this for several situations at customer sites and it works well.
I am not sure what you are trying to do with the two subintefaces (FastEthernet0/0.916 and FastEthernet0/0.917). It appears that you are connected to a switch which has defined two VLANs. But when you put the same bridge group on both subintefaces then you are bridging the two VLANs together and creating a loop.
