The simpliest method would be creating an ACL.

Apply the following ACL on the ports or vlans.

entry BlkMcast {
 if {
 then {
  count BlockedMcast;

This will block also 244.0.0.x multicasts, if you have OSPF or any other routing protocol running you might need to permit that before this block statement.
