Requirement for 2921 to run DMVPN

[Turbo727]

Hi All,

We have cisco 2921 routers as WAN router at each of our branch offices. I am in middle of a design to enable DMVPN over Internet among these routers. As a prerequisite check, can you please let me know whether 2921 fully support DMVPN with OSPF.

Hardware:Cisco CISCO2921/K9

Software:c2900-universalk9-mz.SPA.151-4.M5.bin

License:Securityk9

What else do I need?

Thanks.

The Security-license is all you need. For a new deployment, I would directly upgrade the router to a suggested release, for example 15.4(3)M6a or 15.5(3)M4a.
