slide 20:

2. (50 pts) Consider a network that contains dual-capable IPv6/IPv4 routers (blue) and IPv4-only routers (red). at46:9200:1246 Also, suppose Flows X,Y, and Z that are marked as black solid, black dotted, and gray solid lines, respectively. (a) Draw the datagram structure of Flow X at Node B. (10pts) Hint: Refer to Slide 20 of Module 4 for the datagram structure. (b) Draw the datagram structure of Flow X at Node c. (10pts) Hint: Refer to Slide 20 of Module 4 for the datagram structure. (c) Find the source and destination addresses for Flow Y datagram that is captured at Node B. (20 pts) Note: If the datagram is encapsulated, identify the addresses both in IPv4 and IPv6 format. (d) Find the source and destination addresses for Flow Z at Node c.
