No, in that "VPN" is cited in the scenario and VPN+Mobile IP are not
working well together.
Right - switching between VPN and non-VPN will be important for
enterprise network mobile device users.
I think Alex is referring to the DSMIP and IKEv2 interactions and I don't
believe his point is about switching across VPN and non-VPN modes.
FWIW, the 3GPP S2b interface allows a mobile node to perform handovers
from 3GPP access (S5/S8) to non-3GPP access (S2b).
There are other examples of Mobile VPN solutions that are deployed and are
based on Mobile IP protocols. RFC5265 is only one example.
Sri - I agree that specifications allow certain handovers.
I am not sure what do you mean by Mobile VPN? Mobile IP using a MH-HA
tunnel with a VPN-style tunnel? A VPN which changes the source address
with a new IKE exchange? These are two different things.
In my experience, once I successfully set up a VPN tunnel on a Host
computer its Mobile IP implementation will no longer work, and
vice-versa; although each one can support mobility ok, independently, to
a certain extent.
Alex

Sri
