Which two statements are correct regarding bootstrap messages that are forwarded within a PIM sparse mode domain? (Choose two.)

Answer options

• A. Bootstrap messages distribute RP information dynamically during an RP election.
• B. Bootstrap messages are used to notify which router is the PIM RP.
• C. Bootstrap messages are forwarded only to routers that explicitly requested the messages within the PIM sparse-mode domain.
• D. Bootstrap messages are forwarded to all routers within a PIM sparse-mode domain.

Correct answer: A, D

Explanation

Answer A is correct because bootstrap messages provide dynamic RP information during the election process. Answer D is also correct as these messages are sent to all routers in the PIM sparse-mode domain to ensure they receive the necessary RP information. Options B and C are incorrect as bootstrap messages do not limit forwarding to specific routers nor serve solely to notify about the RP.
