Multipoint VPN design question

Question

Cisco

Good day, dear Khabrovites!

There is a question about VPN design.
At the moment we have a heterogeneous network in four different cities and it is implemented as follows:
Each of the 4 divisions of the company has a Cisco ASA 55xx configured on l2l tunnels to the other ASAs.
Now it is planned to connect at least 6 more objects to the existing architecture.
Now the question arose about the choice of equipment for installation at these connection points.
I ask for advice on the implementation of this event - is it worth buying an ASA 55xx and building to add tunnels, or can it still be better to organize on a DMVPN scheme with the purchase of normal routers?
I apologize in advance for the missed details / inaccuracies. I study cisco networking technologies for only two months.

Answer 1

Well, of course, you should refuse asashek and L2L tunnels if you have money. Tomorrow another 10 points will be added - and a nightmare.
If the implementation is from scratch, then Flex VPN is better right away.
