Abstract
A cross-network-segment discovery method includes: an electronic device A sends, to an electronic device B, a DLNA delivery message including a URL and an identifier of the electronic device B. The electronic device B plays content corresponding to the URL. After the electronic device A moves from an area A to an area B, the electronic device A disconnects from a routing device A and connects to a routing device B. The electronic device A sends, to the routing device B, a first request message including a fixed multicast address. The routing device B forwards the first request message to the routing device A. The routing device A sends the first request message in a multicast mode within a range of a first multicast address. The electronic device B sends a first response message to the electronic device A by the routing device A and the routing device B.
