NAME

       mip6mod - Mobile IPv6 STREAMS Module

SYNOPSIS

       Use the mip6admin utility to start, stop, configure, and manage (see for details).  User applications should not use directly.

DESCRIPTION

       a  kernel-resident  STREAMS  module for Mobile IPv6, implements the Correspondent Node and Home Agent functionality.  The STREAMS moudle is
       responsible for processing and generating all Mobile IPv6 Mobility Header messages:

	      Binding Update (BU),

	      Binding Acknowledgement (BA),

	      Binding Refresh Request (BRR),

	      Binding Error (BE),

	      Home Test Init (HoTI),

	      Care-of Test Init (CoTI),

	      Home Test (HoT),

	      Care-of Test (CoT).

       The following Mobile IPv6 ICMPv6 messages are handled by the IPv6 Router Advertisement Daemon,

	      Mobile Prefix Solicitation/Advertisement (MPS/MPA),

	      Dynamic Home Agent Discovery Request/Reply (DHAAD Request/Reply).

       When the system is configured as a Correspondent Node, supports Route Optimization using the  Return  Routability  Procedure.   During  the
       Return  Routability  Procedure, the Correspondent Node and the Mobile Node  exchange HoTI/HoT and CoTI/CoT messages in order to establish a
       binding management key (Kbm) for authenticating the BU and BA messages.	You can configure to send out  BRR  messages  when  the  remaining
       lifetime of the binding entry drops below the system-configured BRR threshhold value (see for details)

       When  the system is configured as a Home Agent, the IPv6 Router Advertisement Daemon ( ) must alos be running on the system to provide home
       link prefix information to Multiple home links are supported if the correct home link prefixes are configured on each home link interface.

       On a Home Agent, IPsec is used to proctect the signalling messages (i.e. BU, BA, HoTI, HoT, MPS, and MPA) between the Mobile Node  and  the
       Home Agent.  If IPsec ESP is used, the Alternate Care-of Address option must be included within the BU message as the ESP protocol will not
       be able to protect the Care-of Address (i.e. source address) in the IPv6 header.  For troubleshooting purpose, IPsec authentication can	be
       turned  off  on	via  to allow Home Agent to accept plain BU messages from the Mobile Node without out IPsec AH or ESP protection.  You can
       configure to include Binding Refresh Advice (BRA) option within the Binding Acknowledgement from the Home Agent when the remaining lifetime
       of the binding entry drops below the system-configured BRA interval value (see for details).

       For  better  performance  on high-end systems, multiple instances of can be configured to run on the system processing Mobility Header mes-
       sages in parallel (see for details).

       For diagnostics purposes, supports five different levels of diagnostic message logging (i.e. ALERT, ERROR, WARN, INFO, and DEBUG)  via  the
       standard mechanism.  By default, the system is configured to log at ERROR level.

NOTE

       provides  Mobile  IPv6  server functionality (i.e. Home Agent and Correspondent Node).  does not provide Mobile Node functionality which is
       not required on server.
