21.2.3 Multicast Example - Static RP
The concept of setting a static RP involves forcing the PIM protocol to use a specific IP
address as the Rendezvous Point.
Use
“ip multicast-routing” to enter the multicast routing configuration mode and
activate the PIM protocol on the MSBR system.
ip multicast-routing
mode pim
exit
Next, each interface that is used for multicast traffic should be specifically turned on:
interface Fiber 0/1
ip pim sparse-mode
exit
Setting static RP – the join-group packet will be sent to the RP IP address, in case the RP
support the desired group – multicast streaming will be performed.
