Enable multicast at the global config level:-
ip multicast-routing
(Some platforms need ip multicast-routing distributed instead)

Enable multicast routing at the interface config level:-
int vlan 10
 ip pim sparse-mode
int vlan 20
 ip pim sparse-mode

If you need to route multicast across multiple devices its a little more complex and needs a bit more config.

To validate and test, the following commands are helpful.
show ip mroute
show ip igmp groups

For multicast to work properly, you need multicast aware applications.  For general application use, you should generally use an address from the 239.255.0.0/16 range, as these are defined in RFC's as being "administratively scoped".  

FYI, 224.0.1.40 is registered by Cisco as a well known mcast address for RP discovery.  224.0.1.116 is registered by Spectralink as a well known mcast address, i think for voice communications.
