Hi,

First things first : DON'T !
More precisely (for the impact) : https://www.packetmischief.ca/wordpress/wp-content/uploads/2013/04/failure-domain-atomic-bomb.jpg
.. and the related post : https://www.packetmischief.ca/2013/04/02/why-is-there-a-wrong-way-to-interconnect-datacenters/

That being sorted out, 6800 is a switch and should not be expected to do l2tpv3. Same for the 3850, if this is what you mean by "3800". You may try you luck with GREP (Ethernet over GRE), but support on 3850 is "variable" at best (starting with "not supported" - depending on OS version).
