[c-nsp] transparent bridging, correct approach?

[Peter Kranz]

In this situation, I have a single fiber from a remote location carrying 2
VLAN's with 802.1q tags added on the remote side, one is desired to be a
layer 2 bridge for customer traffic (VLAN 116) and the other is for routed
traffic (BGP session, etc with the remove data center) (VLAN 12)..

I envisioned doing the layer 2 bridging part with the 'bridge-group' command
on the sub interface for the customer, but am getting the following errors
in the logs when traffic shows up:

Feb  7 11:33:37: %TBRIDGE-4-INVALIDMEDIA: RFC826_ARP received on
GigabitEthernet1/1.116 - invalid media for transparent bridging
Feb  7 11:33:42: %TBRIDGE-4-INVALIDMEDIA: RFC826_ARP received on
GigabitEthernet1/1.116 - invalid media for transparent bridging
Feb  7 11:33:47: %TBRIDGE-4-INVALIDMEDIA: DODIP received on
GigabitEthernet1/1.116 - invalid media for transparent bridging
Feb  7 11:33:52: %TBRIDGE-4-INVALIDMEDIA: DODIP received on
GigabitEthernet1/1.116 - invalid media for transparent bridging

The simplified config looks like this:

!
interface GigabitEthernet1/1
 no ip address
!
interface GigabitEthernet1/1.12
 description VLAN12 Routed traffic
 encapsulation dot1Q 12
 ip address x.y.z
 no ip redirects
 no ip proxy-arp
 no cdp enable
!
interface GigabitEthernet1/1.116
 description VLAN100 Layer 2 Bridge
 encapsulation dot1Q 116
 bridge-group 100
 bridge-group 100 spanning-disabled
!
interface GigabitEthernet4/2
 description Switched traffic destination
 no ip address
 bridge-group 100
 bridge-group 100 spanning-disabled
!

Looking for advise on the 'right' way to do this..
