Testing for Understanding

To test your understanding of IPv6 mobility, answer the following questions. See Appendix D to check your answers.

  1. How does a mobile node determine its home subnet prefix, home address, and the address of its home agent?
  2. When does a home agent or correspondent node send a binding request?
  3. How does a home agent compile a list of home agents on the home link and then convey that information to the mobile node while it is away from home?
  4. How does the mobile node determine when it has attached to a new link?
  5. What kinds of packets are sent between the home agent and the mobile node?
  6. What kinds of packets are sent between the correspondent node and the mobile node?
  7. What kinds of packets are sent between the correspondent node and the home agent?
  8. Describe the addressing in the IPv6 header, and the sequence of IPv6 extension headers and their contents, for a packet sent by a mobile node that is away from home to another mobile node that is away from home for which a binding cache entry is present.
  9. When does the mobile node send a binding update to the home agent? When does the mobile node send a binding update to the correspondent node?
  10. How does a mobile node determine when it has returned home?
  11. How does the mobile node avoid duplicate address conflicts when it returns home?
