CHAPTER 4: CONTINUE ll. Multicast Routing Consider the network topology in Figure-2 below H1 NET- Router R1 R3 R2 R10 R4 R5 R6 R7 R8 R9 NET-4 NET-3 NET-2 H3 H5 H4 Figure 2: Multicast/Broadcast Topology CHAPTER 4: CONTINUE I. Multicast Routing - Continue Q3. Assume the host H1 is willing to multicast a message to the hosts H3, H4, and H5. Assume a center-based tree approach is used for multicast, R5 is selected as the center, and number-of-hops is used as metric. i. Which routers will need to join the multicast group (i.e. need to send a join request)list the routers in alphabetical order, separated by comma, e.g. R1,R2,R3 i. Draw the multicast tree that will be used. Draw and upload the figure into the next question (use pdf, .doc, .jpg, png, or jpeg) ili. What is the path that the multicast message will follow? Fill the table below to answer this question, following the given rules: List the devices in the route in the order they are traversed, separated by a comma, starting from the source till each destination (the source and destination are already added in the table, you just need to add the other devices); e.g. H1, R1,R3, H3 H3 H4 H5 Path the message will follow to reach the destination H1, H1, H1, H5 Upload the Multicast Tree here.....

R1,R3,R5,R2,R6

R1,R3,R5,R7

R1,R3,R5,R7,R8

2. Draw the multicast tree will be used..?

3. What is the path that multicast message will follow..?

Destination H3,

H1 -->R1,R3,R5,R2,R6 ->H3

Destination H4,

H1--> R1,R3,R5,R7 -->H4

Destination H5,

H1 --> R1,R3,R5,R7,R8 --> H5
