Krishna,
Section 9 of draft-ietf-ipngwg-scoping-arch-02.txt discusses this
very issue. The specific text is:
If transmitting the packet on the chosen next-hop
interface would cause the packet to leave the zone of the
source address, i.e., cross a zone boundary of the scope
of the source address, then the packet is discarded and an
ICMP Destination Unreachable message [RFC 2463] with Code
2 ("beyond scope of source address") is sent to the source
of the packet.
This eliminates problems in forwarding the response to this packet
when the site-local SA would become the DA.
Regards,
Brian
