Restricting PIM Hello

Hi All,

I have a 4948 running PIM and this is connected to a 3560 Layer 2. As the 4948 sends out PIM Hello messages the 3560 marks it as a DR and sends all it’s multicasts to the 4948. Can anyone help on how I stop the hello message getting to the 3650 so the multicasts are not flooded to the 4948??

Is this even possible? The 3560 can't be changed to L3

Many thanks
