I have a situation where I need to get multicast video stream out of a system(sys1), through what will hopefully be a Cisco switch in L3 mode(sys2), to another sytem(sys3) so it can capture the multicast stream. Sys3 cannot be directly connected to sys1 due to security reasons, so it has to go through sys2. Sys1 is already setup with dynamic routing so it should not need any changes. Sys3 is already setup, although at this point I do not know if it is a router or switch(few details at this point) and sys3 traffic cannot be allowed back to sys1, so it has to be stopped at sys2.
Any help would be apprecaited.
