1. The most important task to be performed by the IP layer is ……………………
2. What are the main obstacles for the IPv6 progress?
3. What are the four basic mobility requirements?
4. Discuss open issues in Mobile IPv4.
5. Name the main differences in Mobile IPV4 and IPV6.
6. Mobile IP has been commonly used to allow mobility in networks, especially in heterogeneous network. Describe how mobile IP allows users to move between network boundaries.
7. Mobile IPv4 foreign agents provide ……………….. agent function for a mobile node
that has roamed into a foreign network.
8. Mobile ………………. does not require a local mobility anchor, so no foreign agent exists in a Mobile IPv6 network.
9. Because no foreign agent exists in IPv6, route optimization and …………………. options
are not required for Mobile IPv6.
10. The Mobile IPv6 route optimization capability allows the Mobile IPv6 protocol to coexist with …………… filtering devices located at border gateways.
11. The IPv6 protocol supports neighbor unreachability. This detection can be used in
Mobile IPv6 to assure ………………….. between the mobile node and its default router in the foreign network.
12. Rather than using IP in IP or other encapsulation techniques, the majority of traffic
sent to a mobile node is done so using the …………….. routing header.
13. Mobile IPv6 does not create the same challenges with link layer interactions. Instead of relying on ARP, Mobile IPv6 relies on IPv6 neighbor ………………
14. What are the three modes of home addressing that Mobile IP supports?
15. Describe how dynamic Home Address assignment through local pool works.
16. Draw a diagram showing routing to and from a mobile router.
17. What are the advantages and disadvantages of IPSec over Mobile IP?
18. What is a AAA server? How does it help in a mobile IP deployment?
19. What are virtual networks and why are they used?
20. In a mobile IP, when a Mobile Node moves to another domain, how do the CNs now communicate with the Mobile Node?
