i have a Interworking Ethernet :

Router A:

pseudowire-class EtherAccess
 encapsulation mpls
 interworking ethernet

interface ATM2/0.861 point-to-point
 mtu 1546
 no atm enable-ilmi-trap
 pvc TEST 1/861 l2transport
  encapsulation aal5snap
  xconnect 1101 pw-class EtherAccess

Router B:

pseudowire-class EtherAccess
 encapsulation mpls
 interworking ethernet

interface GigabitEthernet2/0.1100
 encapsulation dot1Q 1100
 no cdp enable
 xconnect 1100 pw-class EtherAccess

The L2 tunnel are up and i see a trafic. I see to:

- On CE B, connected to the Router B, i see the mac address of CE A
- When CE A sent a Ping to CE B, i see on the CE B the packet and i see
the packet answer. But CE A don't see the answer.

Anyone know this problem ? why CE A don't see the mac address of CE B ?
