[nsp] oam-pvc manage packet loss

[sthaug@nethelp.no]

Why do you think it's the OAM configuration that causes packet loss?

If you really mean exactly what you have written here: Try specifying
a traffic class for the first configiuration, ie.

interface ATM8/0/0.205 point-to-point
 ip address x.x.x.x 255.255.255.252
 ip ospf network point-to-point
 pvc 0/205
  vbr-nrt 2048 2048 32
  oam-pvc manage
  encapsulation aal5snap
