PIM Sparse Mode: Static RP
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 Networksâ routers.
The initial PIM sparse mode deployment goals are as follows:
Configure router
PBR
as an RP for the entire multicast address range.Configure all other routers to use
PBR
as the domainâs RP without using BSR or auto-RP.Configure
Cider
to function as a multicast receiver for group 225.1.1.1.Use
Ale
as a multicast source to generate traffic to group 225.1.1.1.Verify RPT join and subsequent traffic-driven switches to SPT.
Figure 10-13 details the portion of Beer-Coâs network that is to be enabled for multicast support. The figure also highlights key aspects of the IGP routing infrastructure now in place.
