I'm doing a very similar simulation, but I have a problem with echo replies on simulator. Ping received but they do not came back. This happens only with one spoke, and after reboot it does with the other spoke, o maybe is a problem or with IOS version or with the c1700 routers...
by the way i have a question regarding the physical connections of the router, are they all connected using a switch on the 200.0.0.0/24 subnet? or did you use a 4th router? thanks in advance for the reply...

Mu setup is multipoint meaning that the hub and spoke routers are in the same broadcast domain and see each other as directly connceted. Each router has 2 EIGRP neighbors and 2 GRE tunnels to other routers. Spoke to spoke tunnel makes it possible to save alots of CPU cycles on the hub and traffic, is simply switched at the hub router, instead of being decrypted and encrypted again for transmision to the other spoke router through the spoint to point tunnel.
I manage a network via GRE over IPsec, which is not a defined as multi point, however all remote GRE peers, do become EIGRP neighbors with single hub.
My question to you, considering EIGRP peering via GRE over IPSec on Internet cloud, how your setup become different from my network setup as mentioned above.
The spoke to spoke tunnel is dynamic in my setup. Which means in this case that when R2 sends traffic destined to R3, the hub router switches the traffic just as any normal traffic through data plane. In point to point without any dynamic spoke2spoke tunnel, the traffic reaches the hub router at the tunnel end and will be decrypted (CPU usage) and again will be encrypted /CPU) for transmission over the second tunnel toward the other spoke router.

Hi there,
It was very interesting to see your setup.
I manage a network via GRE over IPsec, which is not a defined as multi point, however all remote GRE peers, do become EIGRP neighbors with single hub.
