Updated by okurz 4 months ago
## Motivation
See lessons learned meeting #139136. We would again benefit from an easier reproducer. Related to #135818 . Come up with a way to ping over GRE tunnels and TAP devices and openvswitch outside a VM SUT with differing packet sizes.
## Acceptance criteria
* **AC1:** We know how to ping over GRE tunnels and TAP devices and openvswitch outside a VM SUT with differing packet sizes
## Suggestions
* Research upstream about pinging over specific interfaces, GRE tunnels, TAP devices, openvswitch, etc.
* Like `ping -I<interface>` or `ping X.X.X.X%tap0`?
* Checkout network namespaces and if they could be used
* Research about MTU size debugging, tracepath, traceroute, etc.
* Experiment in an openQA-environment or openQA-like with the bridges, tap devices, etc.
* Demonstrate to the team in written form or interactively
* Lookup how the existing check is done via a VM/VNC, and see how this could be simplified
