[quagga-dev 16611] nhrpd / shortcut tunnel not built up

Dear all
I have one DMVPN hub plus two Spokes.
Traffic between hub and spokes is working well but shortcut tunnels 
(spoke2spoke) do not build up.
Maybe not a bug but my very own stupidity (aka. config issue)
Anyone ready to give a hint?
Thanks
