Hi all,

The one of the important thing in IEEE802.16 is missed.
RFC 2462 specifies autoconfiguration in wired-based IPv6 Internet. It did
not specify configuration time.
To use RFC 2462 specfication in IEEE802.16e network, it is
required faster procedure than current DAD procedure.
Has anyone can tell the DAD processing time?

If the IEEE 802.16 network will consume more than one seconds to handover at
IP layer, Does it practical?

So, I would like to propose to add some technical resolution for section
3.1.3 and 3.3.3.

regards,
