How to modify or delete Windows default Multicast routes

How to modify or delete Windows default Multicast routes

  If you have more than one interface on your system and you want to stream video to one network, you should be aware of multicast route .
The default multicast route will be enabled by windows on all interfaces with same metric. So it is hard to tell on which interface it will send the multicast data . For it to send to specific network interface you can delete the route but as is it virtual route the Microsoft wont allow u to delete it . By simple trick you can delete it as follows:
First add the existing route as follows:
Lets say 20.1.1.20 is the network on which you want to delete the route, just add it again on same interface.
c:> route add 224.0.0.0 mask 240.0.0.0 20.1.1.20
Once it is done
c:>route delete 224.0.0.0 mask 240.0.0.0 20.1.1.20
It will delete the unwanted route and send the traffic to destined network.
