Re: [Anima] I-D Action: draft-vanderstok-constrained-anima-dtls-join-proxy-00.txt

Hi Brian.

The answer consists of a selection of text of section 7 of the draft.
The discovery follows the standard coap discovery.
________________________________________________________________
The discovery of the Join-Proxy by the
   Pledge is an extension to the discovery described in section 4 of
   [I-D.ietf-anima-bootstrapping-keyinfra].  In particular this section
   replaces section 4.2 of [I-D.ietf-anima-bootstrapping-keyinfra].

   The Pledge can discover a Join-Proxy by sending a link-local
   multicast message to ALL CoAP Nodes with address FF01::FD.  Multiple
   or no nodes may respond.  The handling of multiple responses and the
   absence of responses follow section 4 of
   [I-D.ietf-anima-bootstrapping-keyinfra].

The presence and location of (path to) the join-proxy resource are
   discovered by sending a MC GET request to "/.well-known/core"
including
   a resource type (RT) parameter with the value "brski-proxy"
   [RFC6690].  Upon success, the return payload will contain the root
   resource of the Join-Proxy resources.
