Large Scale DMVPN

I am in the design phase of a large scale deployment of DMVPN and I would like some info from anyone that is currently using this technology. We will have somewhere around 800 DMVPN endpoints when we are done. 90% of the endpoints will be 871 routers. I would like to know what should we use for the head end router and how many sessions will that router hold. I find documents that the 7200/7600 will hold only 200 sessions. I don't see how that could be the largest device Cisco makes. Will the 3845 hold that many?

I know Cisco uses this so I would assume they have at least 800 endpoints. What does Cisco use.

Thanks for your help

hi

As per the datasheet it can support upto Up to 2500 VPN tunnels but not sure about the simultaneous sessions it can support.
