It has become clear that not every routing member of the mesh ought to announce itself as a Join Proxy. There are a variety of local reasons by which a 6LR might not want to provide the Join Proxy function. They include available battery power, already committed network bandwidth, and also total available memory available for Join proxy neighbor cache slots. There are other situations where the operator of the network would like to selective enable or disable the join process in a particular @@ -96,28 +96,25 @@ This document describes an RPL DIO option that can be used to announce a minimum join priority. Each potential Join Proxy would this value as a base on which to add (decreasing likely hood of attracting traffic) values relating to local conditions.

Protocol Definition The following option is defined to transmission in the DIO issued by the DODAG root. It may also be added by a router on part of the sub- tree as a result of some (out of scope for this document) management function. 6LRs that see this DIO Option SHOULD increment the minimum priority if they observe congestion on the channel used for join traffic. @@ -176,30 +173,31 @@ Options.
