A packet-encapsulated NVGRE is sent from one virtual switch to another virtual switch.
When the DF bit of the outer IP header is set, the packet is dropped by the switch-X
between them because the frame size is bigger than the MTU size of interfaces of the
switch-X. Which action is the correct one to fix this problem without impacting performance?
A.
Change the configuration of virtual switches to use VXLAN instead of NVGRE.
B.
Expand the MTU configuration of the switch-X to accept the biggest NVGRE frames.
C.
Change the configuration of virtual switches not to set the DF bit.
D.
Change the configuration of virtual switches not to send bigger NVGRE frames than the
switch-X interface MTU.
