Question: Consider a mobile node (MN) from network X. The user of MN wishes to communicate with a corresponding node (CN) in network Y. The node

Consider a mobile node (MN) from network X. The user of MN wishes to communicate with a corresponding node (CN) in network Y. The node MN moves from X to a foreign network A. Describe the sequence of messages that are required in Mobile IPv4 so that MN and CN can continue to communicate. Include both the user data messages and the Mobile IP control messages. Now, consider the case where CN moves to foreign network B while MN is still in the foreign network A. Can CN and MN still communicate? Show the message flow to indicate how it will succeed or fail in this case
