Well, yes, why not, anything goes . . .

Currently it's configured using

    http://www.cisco.com/en/US/tech/tk39/tk48/technologies_configuration_example09186a008009455f.shtml

I've tried with and without "atm route-bridged ip" (both seem to work
now, go figure).

And vlan 1 (untagged packets) go through without a problem. I get no
ARP for packets in an other VLAN than 1. I've changed bridge 1
protocol to vlan-bridge, no luck. Going through Troubleshooting
Bridging and IRB over ATM PVCs at

I think I've found a problem, I don't seem to receive BPDUs, even on
VLAN1, and each router thinks it's the root for each VLAN. Maybe the
ATM/Ethernet converter on the CPE side is filtering out the BPDUs,
which it shouldn't. But VLAN1 works... do I really need BPDUs? There
is zero chance of a loop between the CPEs, so...
