Same subnet, different vlans

Hey guys,
 
I'm stumped on this one.
 
Here's the scenario:
 
 
rtr-1 ------------- Cat-1 --- Cat-2 ----------------- rtr-2
  .2 < vlan 2 > < vlan 20> .254
 
| < 192.10.1.x/24 >|
 
 
 
As you can see, both routers are in the same subnet but the ports they
connect to are assigned to different vlan's.
 
There's an 802.1q trunk connecting the Cat's.
 
Broadcast traffic from rtr-1 should reach rtr-2 and vice versa.
 
I thought about 802.1q tunneling and fallback bridging but neither approach
seems to work or be the right way to approach this.
 
Anyone have any ideas?
 
TIA, Tim
