Hello,

sniffering the Binding Updates (Mobile Node in visited network) on my
Home Agent using Ethereal, the packets show a strange structure. The
source address in the IPv6 header is the Home Address HoA of the Mobile
Node and the Home Address in the Destination Option Header is the
Care-of address CoA. Sniffering the Binding Update message on a router
between the MN and the HA, the packet shows the correct structure
(source address is the CoA and the Home Address in the Destination
Option Header is the HoA).

The HA sends often a Binding Error message (error: unknown binding for
home address destination option) together with a Binding Acknowledgement
message (status: binding update accepted). Receiving these messages the
Mobile Node stops MIPv6 operation.

We are using a PC with a dual-core processor for the HA. Might this be a
problem?

Regards,

Dirk
