Vijay, true HA can't prevent MR do whatever it wants with its
addresses. But in order for HA to do proxy-ND for Home Address that
Home Address must be valid on the Home Link. If it's from MNP
then it's not valid on the Home Link.
if the HoA does not belong to the home link and belongs to the MNP,
the Home Agent treats the address as any other address in the MNP. it
does not treat it as an address on the home link. if the HA is using
a route for the MNP (pointing to the MR's current location/tunnel
interface) to do routing for addresses in the MNP, it does the same
for the HoA.
Kind of agree, but I don't understand exactly what you mean. Do you
mean that wherever the HoA is coming from (MNP or home link) packets to
it will actually get routed to the MR? I agree with it. I do have the
picture of a R1 (MR) and R2 (HA) holding a route towards R1's ingress
interface (and not R1's egress). Is it this you mean?
Also I'm confused you saying "if HA uses a route towards MNP" because HA
must always have a route to MNP, be MR at home or away, right?
if the HA using proxy ND to do routing for addresses in the MNP, it
does the same for the HoA.
First, HA can't do proxy-ND for an address that is not valid on its
link, and all addresses derived from MNP aren't valid on the home link.
If HA can't do proxy-ND for the HoA from MNP then HA can't receive
packets addressed to HoA when MR not at home, do you agree?
