Re: dmvpn-phase-1-dual-hub-with-3000-spokes-with-ospf

Hey instead of ASR 1002 why not 1006; this gives the benefits of HA for RP
nd SP, beside placing such equipment as the hub should be more preferred
where you can leverage IPSec encryption features at hardware level of the
ASR nd also achieving great performance buy choosing which SP nd RP base
on your performance needs
