Michael,
 
Please check the nhs defined in spokes... it should be Tunnel ip not the NBMA 
IP... and nhrp mapping.... be carefull in the mapping... it can escape your 
eyes very easily
 
and also check the network advertised in the routing protocol... only advertise 
the tunnel ip network and the loopback network

Hi Everyone – I have got the DMVPN going on Yusuf lab 2.  The tunnels work, but 
both R3 and R5 are losing the DMVPN adjacencies, then they come straight up 
again:
*May  5 06:24:49.271: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 2: Neighbor 172.16.1.1 
(Tunnel0) is down: retry limit exceeded
*May  5 06:24:52.451: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 2: Neighbor 172.16.1.1 
(Tunnel0) is up: new adjacency
Does anyone know what would cause this?
Thanks
Michael
