Question Image

You are configuring multicast routing in a Juniper enterprise network with PIM sparse mode (PIM SM). The network contains multiple routers, and R1 is configured as the rendezvous point (RP). You want to make sure multicast traffic from the sources reaches receivers throughout the network.

With reference to the exhibit, which two configuration elements are required on R2 to provide proper multicast forwarding?

Choose two
Explanation

R2 must enable PIM on the interfaces that participate in multicast routing so it can establish PIM state and forward traffic on the multicast distribution tree. Because R2 is directly connected to the receiver, it must also enable IGMP on that receiver-facing interface to learn the receiver's group membership and generate the necessary PIM join behavior upstream.
