Abstract
In one embodiment, a device in a network identifies a translated source network address for a tunnel source of a tunnel-in-tunnel packet. The device includes the translated source network address within a header of the packet. The header of the packet identifies an inner tunnel that is encapsulated within an outer tunnel during transmission of the packet within the network. The device sends the packet with the translated source network address within the header of the packet.
