Hi,
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
router router
The config I'm trying to use is the following under the fastethernet
sub-interface:
connect connection-name interface pvc interface interworking
interworking-type=20
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,
Rob.
