An MN (Alice) visits the mobile network hosted by the mobile router MR and becomes a VMN

Fantastic news! We've Found the answer you've been seeking!

Question:

An MN (Alice) visits the mobile network hosted by the mobile router MR and becomes a VMN there. Show the route of the packets (in both directions) and how the packet header looks like when Alice communicates with an external CN without route optimization. (You will need to sketch out the nested structure of the packet headers and the corresponding source/destination IP addresses for each layer of the (nested) header along the different legs of the end-to-end path in both directions.

? Network prefixes:

The home link for the mobile router (MR): 2001:0:0:1::/64

The mobile network served by the mobile router: 2001:0:0:1:10::/80

The home link for the mobile node (MN): 3001:0:0:2::/64

The foreign link that MR and its mobile network visits: 5001:0:0:3::/64

? Addresses:

The address of the home agent for MR: 2001:0:0:1::1000

The MR?s home address: 2001:0:0:1:10:78f8:6543:fe (created from MAC address)

The address of the home agent for MN: 3001:0:0:2::1000

The MN's home address: 3001:0:0:2:0:78f8:7642:9dfe (created from MAC address) The correspondent node (CN) address: 4001:0:0:4:0:2000

Consider the same setup as in part 1) except that Alice has performed the standard Mobile IPv6 route optimization procedure with the external CN. Show the route of the packets in both direction when route optimization is in use. (No need to show the packet header structures and addresses).
