Cannot make a BVI on an ATM PVC/catalyst 6500 work!

Hello group
Wonder if anybody has advice on configuring a catalyst we have over here...
["sho ver" is below]

Thanks in advance!

CANNOT make a BVI work.
It has all kinds of VLANs on FEs, and a few GEs.
We added a DS3 ATM ifce, and connected DS3 ATM to our ATM switches.
I want to make it manageable from CLAN [222.1.1.0 address] in the same
manner as I have done other routers in our shop. I manage a bunch of routers
in band ATM on CLAN using BVIs in all the routers, and connected to external
ethernet network.

I got the ds3 up, created PVC, created "bridge group 10 route ip" " int BVI
10," put PVC in bridge group 10. I need bridge encapsulation to use it on
clan.
The config is identical to other routers I have except that I can't seem to
get spanning tree runnng on BVI 10 on this catalyst.
Spanning-tree is default, but it seems to run only on the VLANs ["show
spanning-tree" lists all the VLANs]. When I try to do "bridge 10 protocol
ieee" when I do config - "ieee" is not an option.

When I do "show spanning-tree 10" it says spanning-tree not configured on
bvi 10.
I am not sure the spanning tree is fundamental problem however.

If I am on the catalyst, and I "ping 222.1.1.55," I can PROVE that the ARP
request makes it all the way to the far end 222.1.1.55 and I can PROVE that
the ARP reply makes it all the way back to the catalyst - I have an analyzer
connected to catalyst port. I can even do a debug on the catalyst and see
the stuff. I can do a TCPdump at the 222.1.1.55 and see the ARPs come, ARP
reply go out.

The Catalyst just seems to ignore the ARP reply. It does NOT make it into
the arp cache. Occasionally....... i can actually see the MAC address in
there. If I do a "show bridge 10" I see LOTS of MAC addresses from CLAN,
all saying forwarding. I even see some of the other CLAN IP addresses and
their MAC in the arp cache!?

Here is a "show ip int bvi 10"
NGN2Catalyst-95#sho ip int bvi 10

Here is a "show int bvi 10"
NGN2Catalyst-95#sho int bvi 10
BVI10 is up, line protocol is up
Hardware is BVI, address is 0000.0c55.c434 (bia 0000.0000.0000)

Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0

5 minute input rate 2000 bits/sec, 3 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
L2 Switched: ucast: 0 pkt, 0 bytes - mcast: 0 pkt, 0 bytes
L3 in Switched: ucast: 0 pkt, 0 bytes - mcast: 0 pkt, 0 bytes mcast
L3 out Switched: ucast: 0 pkt, 0 bytes
3143 packets input, 298105 bytes, 0 no buffer
Received 0 broadcasts, 0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
36 packets output, 2160 bytes, 0 underruns
0 output errors, 0 collisions, 0 interface resets
0 output buffer failures, 0 output buffers swapped out

Sure looks like the catalyst is seeing the background bridge traffic coming
in...... Not sure what the packets out is, unless it thinks it sent
something out in response to the ping. Can't believe BPDU bridge packets
are going out since it says spanning tree not running.

Here is a "show ip route 222.1.1.0"
NGN2Catalyst-95# sho ip route 222.1.1.0
Routing entry for 222.1.1.0/24
Known via "connected", distance 0, metric 0 (connected, via interface)
Routing Descriptor Blocks:
* directly connected, via BVI10
Route metric is 0, traffic share count is 1

I am at the end of my rope. If you can think of anything, I would
appreciate it.
I have reloaded the catalyst several times and shut/no shut everything lots
of times.
Thanks.
John
