In the network below, multicast service using PIM-SM protocol has been configured. Assume the group IP address is 239.1.2.3.4. Assume that the sender has yet to send any multicast packets and that the receiver has sent an IGMP Join message to its connected router to join 239.1.2.3.4 Rendezvous Point (RP) S0/1/0 Link R4 3 0 S0/2/0 SO/2/1 Fa0/1 Fa0/o S0/2/1 Receiver sender S0/2/1 R2 R1 Link 2 st 1000 R7 Link 10 Cost 10 Fao/2 Fa0/1 R5 So/1/0 S0/2/0 SO/2/1 Fa0/0 Fa0/1 R3 a) What PIM message is used to create the shared base tree from the receiver to the RP? b) Identify the shared base tree in the diagram (use Router designators and interfaces ids to identify c) Identify the entry in R2's multicast table (in (S,G) notation) d) Identify the entry in RP's multicast table (in (S,G) notation) e) Now suppose the sender transmits multicast packets to 239.1.2.4. What specific PIM-SM message is the entire path) sent to by the sender's DR router connected to the sender to establish the source base tree? f) Identify the source base tree in the diagram (use Router designators and interfaces ids to identify g) Identify the entry in R2's multicast table (in (S,G) notation) h) Identify the entry in RP's multicast table (in (S,G) notation) i) Suppose the source base tree has been established. A IP packet with DA-239.1.2.3 arrives at the the entire path) ingress port s0/1/0 of Router R5. What does Router R5 do with this packet?
