Yes it's very applicable and many customers use DMVPN over the Internet, as primary or backup metod of linking branches together.

the customer has routers 1841 at branches and what router series should be the hub and this customer will merge his company with another company has 20 branches this make 40 branch.

what needed router as hub in case of 20 and incase of 40 branches ?

and if you have any configuration exampels for this case i would be thankful if you provide me with this material ?

thank you

It depends by traffic volume more than number of branches. In general the 1841 is fine unless you want to try to upsell and ISR G2.

Hello Wael. A 3845 ISR router should work fine for the hub. I'm attaching a sample hub and spoke config for your review.

pls rate if this helps.
