Many thanks for your replies Jan, John! I tried translate1-2 and translate2-1, the ingress vlan is getting popped, but the egress vlan stack instead of being (150|200), it became (150|200|200) - i.e. there were three tags imposed on the packet, instead of two. Looking into the issue.
John, by popping and pushing on the same interface, do you mean that call l2vtr_configure twice with pop and push once each respectively?
