addresses are stored in the order in which they are entered. The RP is chosen based on a longer prex match for a
group.

OS10# configure terminal
OS10(config)# ip pim rp-address 171.1.1.1 group-address 225.1.1.3/32

ip pim sparse-mode
Enables PIM sparse mode and IGMP on the interface.
Syntax
ip pim sparse-mode
Parameters None
Default Disabled
Command Mode INTERFACE CONFIGURATION
Usage Information Before you enable PIM sparse mode, ensure that:
• Multicast is enabled globally using the ip multicast-routing command.
• The interface is enabled. Use the no shutdown command to enable the interface.
• The interface is in Layer 3 mode. PIM-SM is enabled only on a Layer 3 interface. Before conguring PIM on the
interface, use the no switchport command to change the interface from Layer 2 to Layer 3 mode.
Use the no form of the command to disable PIM sparse mode.
