Abstract
A source device obtains a data packet that includes both a destination address and a payload. The source device selects an exit point address of multiple exit point addresses corresponding to the destination address based on one or more policies. The source device encapsulates the data packet with a header that includes the selected exit point address, and the encapsulated data packet is provided to the backbone network. The encapsulated data packet is routed through the backbone network based on the exit point address, and an edge router of the backbone network identifies an interface of the edge router that corresponds to the exit point address. The header is removed from the encapsulated data packet, and the data packet is added to a buffer of the interface for routing to one or more other devices outside of the backbone network.
