At this stage, you should have an extensive grounding in IP multicast theory in general, and in PIM sparse mode operation in particular. This knowledge is soon to bear fruit as you configure and validate the operation of PIM sparse mode using a statically defined RP with Juniper Networks’ routers.
The initial PIM sparse mode deployment goals are as follows:
PBR as an RP
for the entire multicast address range.
Configure all other routers to use
PBR as the domain’s RP without using BSR or
Cider to function
as a multicast receiver for group 188.8.131.52.
Ale as a multicast source
to generate traffic to group 184.108.40.206.
Verify RPT join and subsequent traffic-driven switches to SPT.
Figure 11-13 details the portion of Beer-Co’s network that is to be enabled for multicast support. The figure also highlights key aspects of the IGP routing infrastructure now in place.

Details to note in Figure 11-13 include the following:
The default OSPF bandwidth scaling factor is in effect with the
PBR’s end of the
Lager link (asymmetric) and the
