Openshift: Openvswitch vxlan to tunnel devices connectivity issues
Issue
- We identified that when we can ping tunX between machines of same hypervisor but can't ping to tunX between machines of different hypervisors.
- But we need help on this as tunX being created by OpenShift is not accessible so we need isolate on which part the issue is Eg- Openshift or HyperV.
- Seeing some intermittent packet loss between tun devices on Openshift nodes.
Environment
- Red Hat Enterprise Linux 7
