Hi,
Pls let me know if anything is wrong in my
OAM PVC management config. Before adding OAM,
everything was fine. But once i added the
OAM config, PVC went down.
PVC config without OAM management works fine

Modifying the config to include OAM PVC management
brings the PVC down.

I don't have access to ATM switch. Hence i'm not sure
if there is any config in ATM switch which is
dropping the OAM cells between the 2 routers.
