You can configure PIM sparse mode globally or for a routing instance. This example
shows how to configure PIM sparse mode globally on all interfaces. It also shows how
to configure a static RP router and how to configure the non-RP routers.
To configure the router properties for PIM sparse mode:
1. Configure the static RP router.
[edit protocols pim]
user@host# set rp local family inet address 192.168.3.253
2. Configure the RP router interfaces. When configuring all interfaces, exclude the fxp0.0
management interface by including the disable statement for that interface.
[edit protocols pim]
user@host# set interface all mode sparse
user@host# set interface fxp0.0 disable
3. Configure the non-RP routers. Include the following configuration on all of the non-RP
routers.
[edit protocols pim]
user@host# set rp static address 192.168.3.253
user@host# set interface all mode sparse
user@host# set interface fxp0.0 disable
4. Monitor the operation of PIM sparse mode.

Configuring BFD for PIM in ACX Series
The Bidirectional Forwarding Detection (BFD) Protocol is a simple hello mechanism that
detects failures in a network. BFD works with a wide variety of network environments
and topologies. A pair of routing devices exchanges BFD packets. Hello packets are sent
at a specified, regular interval. A neighbor failure is detected when the routing device
stops receiving a reply after a specified interval. The BFD failure detection timers have
