Wrong.

See below how it is stated.

W.r.t. multihoming, neither follows the end to end principle of:

   The function in question can completely and correctly be
   implemented only with the knowledge and help of the
   application standing at the endpoints of the communication
   system. Therefore, providing that questioned function as a
   feature of the communication system itself is not possible.
   (Sometimes an incomplete version of the function provided
   by the communication system may be useful as a performance
   enhancement.)
