Since a mobile node knows its mobile network prefix, it can install

The home agent of the mobile node will know the mobile network

can also install a routing entry when it receives the binding
So, even in
the case 2, we can put a routing entry for the mobile network prefix
by not using any routing protocol.
Please teach the method of not using routing protocol.
Is there draft or RFC ?
Some more minor additional notes...
The above example is for the explicit mode. And if we use implicit
mode, then these two entities already know what to do when
registration completes. So either using a dynamic routing or not is
just a configuration issue for route management and it has nothing to
do with the network model.

I still have my uncertain point.
Please look at the following figures.

I agree as you say, HA and MR can install own routing table entry by
I don't think HA and MR should install routing table entries upon
reception of BU. These routes should be there prior to starting the
However, how do you tell it to other nodes on home
That is a good question. If the route in HA is added only upon
reception of BU then it means if MR1 is at home (if it rarely leaves)
then there's no route in HA1.
R and H should have either a route pointing to MNP through MR1-egress,
or simply a default route through HA1. In this latter case (no MNP
route on H and R), if MR1 is at home, HA1 should send an ICMP redirect
to H and R indicating a shorter route to MNP through MR1-egress.
How do you do when MR1 moves from the home link and the binding message
is completed? Also, how do you do when MR1 returns to the home link?
Yes, good questions.
