It happens on tunnel ingress and tunnel egress nodes (egress = node listed in DA of the packet).

 

Ingress can create whatever header it wants but needs to do fragmentation (and potentially PLPMTUD over the tunnel with the egress).

 

Egress can strip the outer header but not make the inner one bigger, IMO.

 

Is something else being proposed?
