Firewall on the home network
IP-in-IP encapsulation
4:
Draw a diagram showing how packets travel when using reverse tunneling.
5:
What is tunnel path MTU, and why is it sometimes an issue when using Mobile IP?
6:
Describe the Path MTU Discovery mechanism.
7:
What is NAT and why is it a challenge when using Mobile IP?
8:
How is the coexistence of NAT with Mobile IP achieved?
9:
How does the Home Agent infer that a Mobile Nodes is roaming behind an NAT gateway?
10:
Mobile IP and IPSec can coexist with proper configuration and placement of the devices. Draw a diagram that shows Mobile IP over IPSec and IPSec over Mobile IP.
11:
In the previous question, a particular protocol tunnel is contained within the other, that is, Mobile IP over IPSec or IPSec over Mobile IP. In these cases, in what order is the encapsulation removed?
12:

13:
What are the advantages and disadvantages of Mobile IP over IPSec?
14:
Registration Revocation allows for which of the following?
Timely release of Mobile IP resources
Early adoption of domain policy changes with regard to services offered/required of a Mobile IP binding
Timely notification to a Mobile Nodes that it is no longer receiving mobility services, thereby significantly shortening any black-hole periods to facilitate a more robust recovery.
Accurate Mobile IP and resource accounting
All of the above
