We have a switch (Cisco WS-C3750G-48TS) with only a C3750-IPBASE-M image (not a 'C3750-IPSERVICES-M' license). Is there any kind of multicast support here? All I need it to do is route multicast packets to an RP (ip pim sparse-mode). Do we really need the service (C3750-IPSERVICES-M) license/image?. The uplink switch is running C3750-IPSERVICES-M, but this switch doesn't seem to carry any ability to configure multicast on an interface.
