Multicast Protocol for Low-Power and Lossy Networks (MPL)
Parameter Configuration Option for DHCPv6
Abstract
This document defines a way to configure a parameter set for MPL
(Multicast Protocol for Low-Power and Lossy Networks) via a DHCPv6
option. MPL has a set of parameters to control its behavior, and the
parameter set is often configured as a network-wide parameter because
the parameter set should be identical for each MPL Forwarder in an
MPL Domain. Using the MPL Parameter Configuration Option defined in
this document, a network can easily be configured with a single set
of MPL parameters.

1. Introduction
The Multicast Protocol for Low-Power and Lossy Networks (MPL)
[RFC7731] defines a protocol to make a multicast network among
low-power and lossy networks, e.g., wireless mesh networks. MPL has
a set of parameters to control an MPL Domain. The parameters control
the trade-off between end-to-end delay and network utilization. In
most environments, the default parameters are acceptable. However,
in some environments, the parameter set must be configured carefully
in order to meet the requirements of each environment. According to
Section 5.4 of [RFC7731], each parameter in the set should be the
same for all nodes within an MPL Domain, but [RFC7731] does not
define a method to configure the MPL parameter set.

RFC 7774 MPL Configuration for DHCPv6 March 2016
Some managed wireless mesh networks may have a DHCP server to
configure network parameters. MPL parameter sets shall be considered
as a part of network parameters (nodes in an MPL Domain should use an
identical parameter set). A parameter set is required to configure
an MPL Domain.
This document defines a way to distribute parameter sets for MPL
Forwarders via a new DHCPv6 [RFC3315] option. This document is
intended to follow the guidelines provided in [RFC7227].
