interface.

console(config-if-vlan15)#ip multicast ttl-threshold 5
ip pim
Use the ip pim command in Interface (VLAN) Configuration mode to
administratively configure PIM mode for IP multicast routing on a VLAN
interface. Enabling or disabling PIM mode concurrently enables/disables
IGMP. Use the no form of the command to disable PIM on the interface.

no ip pim

User Guidelines
PIM requires that routing and multicast routing be enabled. Enabling PIM
enables IGMP/MLD. Disabling PIM may operationally disable multicast
routing.

console(if-vlan-10)#ip pim
