Disclosed in the present invention are a method and device for realizing communication between an NVO3 network and an MPLS network for achieving cross-domain communication between the NVO3 network and the MPLS VPN network. In some possible embodiments of the present invention, the method comprises: obtaining, by an ASBR in the NVO3 network, the PE device identity in the MPLS network and the MPLS label allocated by the ASBR in the MPLS network, wherein the MPLS label will be used as the outer label of an MPLS encapsulated packet sent from the ASBR in the NVO3 network to the PE device; allocating an IP address for the MPLS label from a local address pool, and storing the correspondence between the MPLS label and the allocated IP address; transmitting route information to an NVE, the route information comprising the PE device identity and the allocated IP address, and the allocated IP address is used as the outer destination address of an NVO3 encapsulated packet sent from a TES in the NVO3 network to a CE device connected to the PE device in the MPLS network. |
