as DMVPN, (NHRP/GRE) is configurable on SarOS devices (however, the operation guide does not describe it), I assume, the new generation of Digi OS will support it as well.
On the other hand, what solution would you recommend to use int case of TX54 spoke nad cisco ASR HUB constellation to minimize configuration.
I assume dVTI/IPsec on cisco or DMVPN/NHRP.
Any use-case, best practice?
This would be an 2000+ Digi/spoke dual active LTE WAN design.
