I wonder if anyone else has run into this problem before.
I have a client using a vMX in Azure and they are reporting 4% packet loss to all the VMs in Azure from the spokes. It doesn't matter which VM is being pinged, and it doesn't matter which spoke the ping is being done from. Spokes can ping other spokes with zero packet loss.
The issue happens consistently 24x7. You do about 100 pings and you will loose about 4 of the packets. The packet loss tends to be spread out.
If you do a ping within the Meraki dashboard there is zero packet loss between the vMX and any spoke that I test. There are no interesting events in the event viewer, and the status bar for the vMX and spokes is solid green.
The VMs in Azure can ping the vMX with zero packet loss. The issue only happens when traffic is routed through the vMX to a remote spoke (or from a remote spoke being routed through the vMX to the Azure VMs).
The vMX and all MX's are running 14.39. I have tried rebooting the vMX and a small selection of MX's. I have also had a small number of the Windows VMs rebooted. The VMs are running different versions of Windows Server as well (so there is nothing in common).
Nothing has made a difference.
Any one had issues with small amounts of packet loss to VMs in Azure connected via a vMX?
