ip pim dense-mode
Or sparse-mode, depending on what you want to do? That makes
it so that your ethernet will get multicast packets, and machines that
do a /sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
will see the traffic.
That's our configuration here. If you have a access-list (firewall)
configured on the router, add this to your permit section also:
access-list XX permit udp any 224.0.0.0 15.255.255.255
