1. Introduction
RPL [RFC6550] specifies a proactive distance-vector based routing
scheme. The protocol creates a DAG-like structure which operates
with a given "Mode of Operation" (MOP) determining the minimal and
mandatory set of primitives to be supported by all the participating
nodes.
This document adds a notion of capabilities using which the nodes in
the network could inform its peers about its additional capabilities/
features. This document highlights the differences of capabilities
