I'm a beginner, but found so far that the original mpath dump shows
entries for:

(1) directly reachable nodes
(2) announced root if any
(3) announced gate if any
(4) dynamically resolved nodes (in a mesh)

My patched iw;

shows entries for

(5) proxy'ed nodes behind gates

also.

I don't think so.

I believe that there is no easy way of enumerating all nodes in a mesh
using layer 2 facilities only.

My guess is that we can make a small program that listens to broadcasted
frames transmitted by nodes in a layer 2 network from time to time.
This will probably capture most nodes running actively transmitting IP
based programs because they need to broadcast ARPs, but not inherently
silent nodes.

Another small program on all nodes in a network that periodically broadcast
heartbeat(?) frames may help the first program to find more nodes.

The latter program can be as simple as pinging an arbitral node in the
overlay IP network (which will broadcast an ARP for that node).
