hardware-drop-disable

Disables passive multicast route insertion (PMRI).
Syntax
hardware-drop-disable
no hardware-drop-disable
Command Default

PMRI is enabled.

Modes

PIM router configuration mode

Usage Guidelines

The no form of this command restores the default and enables PMRI.

To prevent unwanted multicast traffic from being sent to the CPU, PIM routing and PMRI can be used together to ensure that multicast streams are forwarded out only on ports with interested receivers and unwanted traffic is dropped in hardware on Layer 3 switches. To disable this process, use the hardware-drop-disable command.

Note: Disabling hardware-drop does not immediately take away existing hardware-drop entries, they will go through the normal route aging processing when the traffic stops.
Examples

This example disables PMRI.

device(config)#router pim
device(config-pim-router)# hardware-drop-disable
