Abstract
In one embodiment, a device in a network receives a packet that includes a forwarding label for a service in a service chain. The packet encapsulates a service chain header for the service chain. The device swaps the forwarding label for the service in the packet for a reserved label that identifies the packet as encapsulating the service chain header. The device forwards the packet with the reserved label to the service.
