the TR receiving the LISP single-layer data packet, analyzing and encapsulating the single-layer data packet into a LISP double-layer data packet and sending to an interworking service node (ISN), wherein in the LISP double-layer data packet, an outer source address is a router locator of the LISP communication end, an outer destination address is a router locator of the Internet communication end for intercommunicating with the LISP network, an inner source address is the endpoint identity of the LISP communication end, and an inner destination address is the endpoint identity of the Internet communication end for intercommunicating with the LISP network;
after receiving the LISP double-layer data packet, the ISN analyzing and encapsulating the LISP double-layer data packet into an IP data packet, wherein in the IP data packet, a source address is an IP address of the LISP communication end for intercommunicating with an Internet, and a destination address is an IP address of the Internet communication end; and
the ISN sending the IP data packet to the Internet communication end through routing;
thereby realizing intercommunication between the LISP network and the Internet.
