Problem on multicast with cisco routers

According to the materials of the 5th Russian Olympiad cisco, where I had the opportunity to participate in inventing and testing puzzles for the finalists, the following difficult task was born:

Consider the simplest scheme:


')
there is a cisco router, a computer with a program that receives streaming (for example, VLC Player) is located behind one interface, and a transmitting station broadcasting a stream (for example, video) to some multicast address is located behind the other interface.

You can change the multicast address of the stream to which the server is broadcasting.

Task 1: Is it possible to force a computer to accept a stream without resorting to multicast routing?
Task 2: Is it possible to force a stream to be accepted with the condition that you don’t know what a multicast is, how it works and how it is configured?

Threat This atypical puzzle (second version) of 30 people was decided by 1.5 people. I wonder if you decide, because your level is significantly higher than CCNA, which all Olympiad participants are.

Threat If you want to speak, but are only a reader habra, go to the forum on the site www.anticisco.ru , where in the section "Problems for ingenuity" it is duplicated. Registration on the site is simple.
