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

  -----+-----+-----+-----+----- Home Link: A:B:C:0::/64
       |     |           |
       |     |           | MR1-egress
       H     R(MR)       MR1
             |           | MR1-ingress (Home Address)
                        -+----- Mobile Network: A:B:C:i::/64

I agree as you say, HA and MR can install own routing table entry by
binding message. However, how do you tell it to other nodes on home
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?

Best regards
