Two
address expirations
|
|
|
– |
DHCP
lease (IP addresses are leased for a limited time, need to be
|
|
renewed
periodically)
|
|
|
– |
Home
Agent binding will expire
|
|
|
– |
Ideally:
make DHCP lease and binding lifetime same (usually
|
|
|
means
that DHCP lease will be shortened, since leases are usually
|
|
|
rather
long-lived for desktops and other stationary devices)

Dual-mode
operation: FA or DHCP?
|
|
|
|
– |
Less
address maintenance is required when using FA care-of-
|
|
|
address
(no DHCP lease renewal)
|
|
|
– |
FA
may be equipped to handle decapsulation efficiently
|
|
|
– |
FAs
may cooperate to provide smooth handoffs
|
|
|
– |
packets
for MH decapsulated before wireless link, reducing

bandwidth
