> - The iperf command
Just sending traffic from one geneve interface to the other.
iperf -c <ip of remote geneve> -i1 -t10
iperf -s # on the server side
The geneve tunnel is created using:
ip link add <dev> type geneve id 464 remote <ip>
> - Your network topology
Just back-to-back NICs on two VMs.
Please let me know if you need anything else.
