Multicast Traffic Reduction Per Vlan - Dell PowerConnect B-RX Configuration Manual

This command enables IP multicast traffic reduction. The active | passive parameter specifies the
mode. The PIM SM traffic snooping feature assumes that the network has routers that are running
PIM SM.
Syntax: [no] ip pimsm-snooping
This command enables PIM SM traffic snooping.
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

With release 02.6.00 of the Multi-Service IronWare software, you can configure specified VLANs
instances for multicast traffic reduction by these methods as described in the following sections.
Additionally, release 02.6.00 introduces PIM proxy which are only configurable per VLAN instance.
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 an BigIron RX 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 an BigIron RX 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
