Abstract
An ingress router of a provider network receives a packet from a customer network, determines that the packet includes a customer network label and that the packet is to be tunneled through the provider network, based on the determination, adds a delimiter label to the packet indicative of a bottom of a provider network label stack and one or more provider network labels to the packet, and forwards the packet to a next routing device along the provider network tunnel. An egress routing device of the provider network receives a packet comprising a provider network label stack, removes the provider network label stack from the packet, determines whether the packet comprises a delimiter label following the provider network label stack, and, when the packet comprises the delimiter label, forwards the packet to a customer network interface device.
