[OOR-Users] Received control message with type 7. Discarding!

[José Miguel Guzmán]

Albert

Thanks a lot for your clarification

I was not aware of lisp-nat-traversal draft
<https://tools.ietf.org/html/draft-ermagan-lisp-nat-traversal-11>
Disabling nat traversal, fixed this problem, but introduced the problem
that it does not work behind NAT :)

Using OpenDaylight Lisp Flow Mapping:Main
<https://wiki.opendaylight.org/view/OpenDaylight_Lisp_Flow_Mapping:Main> with
OOR, is a viable solution for NAT?

Muchas Gracias
JM
