Hi all,
I working with openvswitch 2.5.3 (tried with 2.11.0 same behavior) on
XCP-ng (XenServer fork).
I'm trying to undersand how the mtu works with GRE and VxLAN tunnels.
As for now when I create a GRE tunnel with any MTU, I think the MTU is
not taken in consideration because i can ping -s 15000 on the
corresponding interface.
However, with VxLAN if I set a MTU greater than 1450 then the MTU is
1450 and if I set a MTU lower than 1450 I have same behavior as for GRE.
So I'm a but confused.
When I check the mtu value with : ovs-vsctl get int xapi0 mtu_request or
ovs-vsctl get int xapi0 mtu the returned value is what I expect.
Thanks in advance,
Benjamin
