Abstract: A first customer edge network device receives an encapsulated packet that includes inner headers comprising source address information for a first service running on a first computing apparatus in a first home cloud and destination address information for a second service running on a second computing apparatus in a second home cloud. The customer edge network device inserts a predetermined portion of bits of a virtual domain identifier of the encapsulated packet into a label to form a virtual domain label for label-based routing. The virtual domain label is appended to the encapsulated packet. The encapsulated packet is sent to a first provider edge network device of a provider network. The first provider edge network device appends an virtual private network label to the encapsulated packet, and sends the encapsulated packet to a provider network device for label-based routing in the provider network.
