Yes, I am convinced that is the case. Must be down to a config issue.

I added the topology as well: don't get distracted by the swifes. Those
are just tunnels to the dlep_bound briged radios. The router get the
mcasts(hellos) from each other via our waveforms. I can confirm that.
The packets are fine as far as wireshark can tell. So it must be a
config issue! 

Thanks!
