ALain,

Let's describe how the RA packet sent from Y4/Y6 to X6 is handled. The
encapsulated RA packet has the following layout:

SRC = Y4/Y6
DST = X6
NH = IPv6
    SRC = Y4/Y6
    DST = ff02::1
    NH  = ICMP V6
         RA message

When this packet arrives on X6 (DST = X6), X6 decapsulates the first
IP packet .
This packet is then reinjected into the IP stack, since the NH = IPv6
(Next Header).

This RA packet (decapsulated), with DSTM specific option, will be
handled by the DSTM client contained in the X6 Host
to configure the DTI interface as depicted in
draft-ietf-ngtrans-dstm-05.txt chapter 3 and following.

Then, the DSTM classic mechanism applies.

Hoping this clarify the solution,
Best regards,
