Main expansion of MIPv6 to HMIPv6

After reading the Draft, you summarize it, it is not necessarily accurate, but it is basically almost

Baotou and message format change

Increase M bits, used to register to Map Neighbour Discovery has a new structure for MAP.

Mn Mn is the focus of improvement, most improvements occur here.

The MAP is found from the RA of ROUTER, selecting the highest perference value. The selection is from far away (coverage) MAP, which can reduce the number of switched occurrences. If in the same map, just re-entertained LCOA, if you enter new MAP, use the Stateless mode, generate new RCOA to MAP to send local bu: M and A bit, is a bu, RCOA put To the location of Home Addr, there is no need Alternate-CoA, LCOA is the source address. Before registering new MAPs, you should use new LCOA to make Local's Bu, which reduces packet loss. MAP performs DAD and send it back back. There is no new definition error code, it is original. If the returned ACK does not contain the routing head of Type2, ignore it. All transmitted packages are sent to the MAP through the tunnel, the outer head LCOA -> Map, and the internal address is used as the original address in RC OA. You can bind multiple maps, but you can't nested, which will reduce protocol efficiency and performance. (Draft -ietf-mipshop-hmipv6-03.txt, october 2004, pp. 10, pp.16) After the MAP is bound, use RCOA to HA and CN, of course, by MAP. Lifetime for BU to HA and CN cannot be larger than the MAP. The package is subjected to the package by the tunnel. Can not pass Map.

Map Map is existing as a local HA, and its core work is to perform a tunnel operation, it doesn't know who HA is.

Accepting the registration of the MN, returns the confirmation information, must return the routing head of Type 2; this to refer to MIPv6 to HA, two-way tunnels with MN. (Like HA), using Neighbour Advertisement to intercept the RCOA package, send them to LCOA through the tunnel.

Router (BS) forwards the MAP's advertisement information. If you are MAP, you will add yourself. If you have repeated, you will choose the distance value low. (This is not necessarily support, but can tell Map through RA should be required).
