Back in 2017, I started on an embedded router project, but shortly after, it was put on indefinite hold. Recently however, it has started up again and I needed to run some performance tests on a DMVPN (using iperf3). We had received an evaluation license back in 2017, but since we shut it down, the license says we still have a few weeks left. However, when running tests across the DMVPN (GRE tunnel), the first few packets go ok, then almost everything after gets dropped.
So my question is, are the packet drops likely due to the license, or a configuration problem?
I've attached iperf results and license info:

Hello,
in theory, the evaluation license should provide full functionality until the expiration date. Can you post the config of both hub and spoke of the DMVPN, in order to verify that those are ok ?

Thanks for your reply.

Hello,
the configs look fine, just a few minor things(marked in bold).
When you issue the exec command:
show platform software license
What is the current enforcement forwarding rate ?
And what are your options with the command:
5921(config)#license platform throughput level ?

Thanks for the reply.
I removed the routes, but now my hosts at 192.168.8.101 and 192.168.9.101 can't see each other to run iperf.
