IPSec and GRE - terminate on the same device or different devices?

Last Modified: 2012-05-08
I am looking at cisco's DMVPN running IPSec over GRE tunnels to allow multicast. I can't locate any pro / con discussion about terminating the IPSec and GRE tunnels on the same device or different devices. If I have the resource (CPU and bandwidth) to handle the load, are there operational or manangement considerations I'm missing?

Thanks for your input.
