Comment (by cgarcia):

 Boost examples are wrong, doesn't work in linux for machines with several
 network interfaces. Proper truly working code snippet for receiving on
 network interface 1.2.3.4:

     std::string address_listen = "1.2.3.4";
     std::string address_mcast = "224.0.0.0";
     unsigned short address_port = 50000;
     boost::system::error_code ec;
     boost::asio::ip::address listen_addr =
 boost::asio::ip::address::from_string(address_listen, ec);
     boost::asio::ip::address mcast_addr =
 boost::asio::ip::address::from_string(address_mcast, ec);
     boost::asio::ip::udp::endpoint listen_endpoint(mcast_addr,
 address_port);
     socket.open(listen_endpoint.protocol(), ec); //
 boost::asio::ip::udp::socket
     socket.set_option(boost::asio::ip::udp::socket::reuse_address(true),
 ec);
     socket.bind(listen_endpoint, ec);
 socket.set_option(boost::asio::ip::multicast::join_group(mcast_addr.to_v4(),
 listen_addr.to_v4()), ec);
