Recently, i got some hints on the forum to get my 2 ATM PVC's to bond together via bridging on a 7204VXR. This is working now and i can ping from left to right and ARP seems to work ok.
Now i attached 2950's on both sides and configured a VLAN trunk on the interfaces facing the DSL network. Unfortunately, there's something going wrong in replying to ARP.
When trying to send something from A to B, there's an ARP request going to B. B replies with it's MAC, but this reply is not received by A. I included a packet capture and a diagram so you guys can see what i'm talking about. 7200 config is pretty straightforward :
interface atm1/0.162055 point-to-point
interface atm1/0.162056 point-to-point
bridge 10 protocol ieee
Any help would be very appreciated.
