What licenses are required to use cisco dmvpn with encryption?

Question

VPN

Hello, I plan to organize a VPN in an organization.
Having read about dmvpn + ipsec, I want to buy a Cisco 2851 in the central office and several Cisco 800 in the branches.
The question is whether there are any pitfalls associated with licensing?

Good afternoon.

Licenses on ISR G1 routers are determined by the uploaded firmware file.
Are you sure that 2851 as a hub and 800 as a spoke will be enough for you in terms of performance? What is the width of your links in the CO and branches? How many branches will there be?
