Hello everybody,
I´m doing some measurements in order to optimize the Handover delay for
MIPv6. 

I´m using a notebook (as a mobile Node) with a W-Lan interface and trying to
do a Handover from the first wireless network (Homenet placed on the
HomeAgent) to a Foreign Network (visitnet1 placed on a second Computer:
CoreRouter).


I´m making measurements of the router Discovery Procedure. That means
beginning at the Moment the MN already finished connecting to the new Wlan
Network (on Layer 2) and starts looking for a router in the network (by
sending the first Router solicitation message)


I used wireshark to trace the traffic generated on both sides, and as we see
here, some of the packets send by the CoreRouter (fe80::216:6fff:fe1d:b521)
don´t arrive at the Mobile Node.

All the machines are in the same room, that means no problems with signal
level (always higher than 70 %)

Any Idea?

Hakim
