Example 2 for Configuring PIM-SM

In the following topology, Switch B is the C-BSR and C-RP. Host A is a receiver for multicast traffic, and Host B is a multicast source that will send the multicast traffic.

You'll need to configure ge-1/1/2 as an IGMP interface in Switch A for Host A.

In this example, the static route in the RIB will be used by PIM-SM. 


 
                  Figure 8-1. PIM-SM multicast routing configuration. 


Configuring Switch A

For switch A, configure ge-1/1/2 as an IGMP interface and ge-1/1/1 as a PIM-SM interface.

Configuring Switch B

Configure 2 PIM-SM interfaces, ge-1/1/1 and ge-1/1/2. You will also need to configure a candidate BSR and a candidate RP.
