Thank you.

Jumbo frames are not just nice but required. VXLAN doesn't play well with fragmentation. The network operator needs to have them in place in between the VTEPs / Virtual Tunnel End Points.

I know of a couple of providers whose networks are VXLANs. Their customers ride on the technology right now.

Understood. With headers that huge… I was thinking of the real 9k jumbo frames rather than eg 1600 bytes ‘baby’ jumbos - that probably wouldn’t be big enough ? Especially not for the header stacks that contain IPv6 headers?

VXLAN adds 50 bytes. 1600 should be just fine though can be set higher if desired.

By the time it leaves the VTEP at the other end it'll come out with the same MTU requirements it entered the VXLAN with.
