With reference to the exhibit, which two statements are correct?
In PIM sparse mode, an (S,G) entry identifies the multicast distribution tree for one specific source and group. An upstream “Prune to Source” state at the RP means the RP has pruned traffic for that specific (S,G) pair toward the source because it has no downstream interest in carrying that source’s traffic through the RP. The shared (*,G) state still represents the RP-based tree for the group and is independent of pruning one particular source. Cisco documents that (*,G) joins are sent toward the RP, whereas (S,G) joins are sent toward the source, and that a prune removes the relevant path from the distribution tree.
