In the exhibit, the 10.100/16 prefix is introduced at autonomous system 1 (AS1) and propagated
through to AS3. Router A in AS3 receives two different paths to these prefixes, one through AS2
and the other through AS4. No BGP attributes have been altered.
Which path would router A prefer for the 10.100/16 prefix?

In the exhibit, the routers in the network have a default PIM sparse mode configuration. R2 shows
that R1 is the RPF next hop for the source, and R3 is the RPF next hop for the RP. Host1 is
currently receiving multicast traffic for group 231.1.1.1. Host2 has come online and is attempting to
join group 232.1.1.1. R2 has just received an IGMP message with the source and group
addresses.
Which step happens next so that Host2 can join the multicast group?
