The correct answer is A. When maintaining the multicast distribution tree, you can continue to send multicast packets to ensure that multicast routing table entries can always exist. B. When building a new multicast distribution tree, routers do not need to send Join/Prune messages to the upstream of the multicast routing table entries. D. The final formation of a multicast distribution tree mainly relies on the diffusion mechanism, pruning mechanism, assertion mechanism and DR election mechanism. See the full explanation below for the reasoning.
Question
Which of the following descriptions of the PIM-DM multicast distribution tree are correct? (Multiple choice)
A. When maintaining the multicast distribution tree, you can continue to send multicast packets to ensure that multicast routing table entries can always exist.
B. When building a new multicast distribution tree, routers do not need to send Join/Prune messages to the upstream of the multicast routing table entries.
C. The status does not change. The multicast distribution tree will always exist and remain unchanged after it is formed.
D. The final formation of a multicast distribution tree mainly relies on the diffusion mechanism, pruning mechanism, assertion mechanism and DR election mechanism.
