1.  Introduction

   Multicast Protocol for Low power and Lossy Networks (MPL)
   [I-D.ietf-roll-trickle-mcast] defines a protocol to make a multicast
   network among low power and lossy network i.e. wireless mesh
   networks.  MPL has various parameters to control its behavior and
   tradeoff between end-to-end delay and network utilization.  In some
   environments, the parameters shall be configured carefully to meet
   each environment and requirement.  According to the MPL draft section
   5.4, the parameter should be same for all nodes within an MPL domain.
   And the MPL draft does not define a method to configure it.

   Some managed wireless mesh networks may have a DHCP server to
   configure network parameters with DHCP relay in each node.  MPL
   parameters shall be considered as a part of network parameters
   (parameter shall match within an MPL domain).  This document is to
   define the way to distribute parameters for MPL forwarders as a
   simple DHCPv6 [RFC3315] option.

2.  MPL Parameter Configuration Option

   Per MPL domain, there are following 10 parameters.  An MPL domain is
   defined by an MPL domain address.

   o  PROACTIVE_FORWARDING

   o  SEED_SET_ENTRY_LIFETIME

   o  DATA_MESSAGE_IMIN

   o  DATA_MESSAGE_IMAX

   o  DATA_MESSAGE_K

   o  DATA_MESSAGE_TIMER_EXPIRATIONS

   o  CONTROL_MESSAGE_IMIN

   o  CONTROL_MESSAGE_IMAX

   o  CONTROL_MESSAGE_K

   o  CONTROL_MESSAGE_TIMER_EXPIRATIONS

   One network may have multiple MPL domains with different
   configuration.  To configure plural of MPL domains via DHCP, there
   may be more than one MPL Parameter Configuration Option given to DHCP
