hi,
so it highly depends on the underlay chosen... those that propagate 
explicitly the upper layer's ethertype, will work..
examples include vlan, gre and l2tp, all with or without macsec... those that 
dont, like ipip and wireguard, can only carry
ipv4 or ipv6 because on the receiving side, one can only have the first 4 
bits to _guess_ the upper layer protocol...
br,
