7200 local switching interworking between Ethernet Vlan to ATM

[apisak_num]

I want to bridge traffic between ATM interface to Ethernet interface on Cisco7200 as show in attached file. What I want to do in this case is they want to have PVC between 7600 to 2811 . But on the 7600 side is the FEthernet VLAN 802.1q connect to 7200(is the xconnect tranparent bridge) . On the other side 2811 is the CPE connected to FR/ATM network.

I'm trying to think of the best simple way to do this . One of an idea is , Can I use 7200 to perform like SP PE router and do L2VPN local switching on that box ? But I'm not sure if it will work or not. My question is .

1. Can we do local switching on 7200 with L2 interworking between Ethernet VLAN and ATM PVC ?

2. Do we need to configure MPLS or L2TPv3 in this case since there is no MPLS network ?

3. Which IOS is required on 7200?

Or if you have any other suggestion to make the point to point configuration on 7600 to 2811 , please advise.

Thank in advance.

This is a same proplem :

I'm trying to get the ATM to ethernet VLAN local switching working properly.

What I'm trying to achieve is to connect a Cisco 828 over an SDSL line using

a VP/VC that terminates on a Cisco 7200. This VC is then connected at layer

2 on the 7200 to a VLAN, which eventually terminates on a Cisco2621.

Physical view:

828 ____SDSL ____ ATM ____ 7200 ____VLAN____ 2621

router DSLAM cloud router router

I can get the 828 to talk to the 7200 at layer 3 no problem, but what I'm

trying to do is get the 828 to see the 2621 as being directly connected at

layer 3 (i.e. the 7200 is transparent). Here is the logical (layer 3) view:

828 ____ 2621

The config I'm trying to use is the following under the fastethernet

sub-interface:

connect connection-name interface pvc interface interworking

interworking-type

This is described in more detail here:

I'm not having any joy getting this working, so I was wondering whether any

of you have had any experience with this and can help me out?

The 7200 is a 7206VXR running IOS 12.2(25)S1.

Thanks in advance,
