BUG VXLAN and MTU

[andaga]

Hello,

Why we need setup the MTU of the SDN zone into the settings and into the NIC interface of the VM when we select the "bridge" concerning the VXLAN the MTU by default is 1500?

Normally for VXLAN the MTU need to be 1450 as configured into the capture attached!

It's a bug? Why we need setup it again manually into the NIC interface?

You don't need to setup it again, it is only a visual bug since 1500 was the default MTU for everything before SDN.

Unfortunatly it not work with correct MTU! We need absolutly put the value 1450 into the NIC interface! So it's not only a visual bug!

Ah sorry, I've only looked on the host where tap interfaces get created with the proper MTU, but it seems like in the VM the interface has an MTU of 1500 - I'll look closer into it. Thanks for reporting this!
