Which two statements are associated with any-source multicast? (Choose two.)
A.
Routes learn the source of the multicast traffic from the source address of the multicast traffic.
B.
Routes learn the source of the multicast traffic from the receives.
C.
Routes do not specify a specific source from which to receive traffic.
D.
Receives select a specific source from which to receive traffic.
Explanation:
An any-source multicast (ASM) network must be able to determine the locations of all sources for a particular
multicast group whenever there are interested listeners, no matter where the sources might be located in the
network. In ASM, the key function of source discovery is a required function of the network itself.
Multicast source discovery appears to be an easy process, but in sparse mode it is not. In dense mode, it is
simple enough to flood traffic to every router in the network so that every router learns the source address of
the content for that multicast group.
