To disable the feature, enter the following command.
BigIron RX(config)# no ip pimsm-snooping
If you also want to disable IP multicast traffic reduction, enter the following command.
BigIron RX(config)# no ip multicast
Multicast traffic reduction per VLAN
You can configure specified VLANs instances for multicast traffic reduction by these methods as
described in the following sections.
Configuring the PIM SM traffic snooping per VLAN
In the following example, multicast traffic reduction is applied using PIM SM Traffic snooping to
VLAN 2.
BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# multicast pimsm-snooping
Syntax: [no] multicast pimsm-snooping
Configuring PIM proxy per VLAN instance
Using the PIM proxy function, multicast traffic can be reduced by configuring a device to issue PIM
join and prune messages on behalf of hosts that the configured router discovers through standard
PIM interfaces. The router is then able to act as a proxy for the discovered hosts and perform PIM
tasks upstream of the discovered hosts. Where there are multiple PIM downstream routers, this
removes the need to send multiple messages.
To configure a device switch to function as a PIM proxy on VLAN 2, use the following commands.
BigIron RX(config)# vlan 2
BigIron RX(config-vlan-2)# multicast pim-proxy-enable
Syntax: [no] multicast pim-proxy-enable
Displaying IP multicast information
The following sections show how to display and clear IP multicast reduction information.
Displaying multicast information
To display IP multicast traffic reduction information on the device, enter the following command at
any level of the CLI.
