Hi,
I have what is probably a dumb question so it should be an easy one
for gurus.
I built two VM's on VirtualBox using my Orabuntu-LXC software. The VM
VNIC's are ports on OvS sw1 on each VM. The VM's are on the same
physical host. I have LXC containers on the sw1 switch also. What
has surprised me with this setup is that I can ssh between containers
that are on different VMs and all the network devices, the VNIC's and
the OvS switches, and the physical interface on the host, are all set
to MTU 1500. Not anywhere in this setup is MTU 1420 used. My
understanding was, and what I have found in all previous cases, was
that I had to use MTU 1420 for ssh over a GRE tunnel to allow for
encapsulation, so my question is I am wondering how can ssh be working
over this GRE tunnel when all the MTU of all devices is set to 1500?
ssh will use smaller packets for most terminal oriented applications.
Perhaps you're not exchanging traffic with larger packet sizes.
Try iperf or something like that which will use maximum size MTUs
