i'm having trouble setting up intervlan multicasting on a catalyst 4510R.
multicast within the same vlan works fine but after putting the source in a separate vlan i cannot get it to work.
ip multicast-routing is enabled
and ip pim sparse-mode is set on the vlans in question
i have tried dense-mode, adding an RP address. pretty much everything
i'm sure i've missed something simple as it doesn't seem that difficult a thing to set up!
could someone help me with the config?
