effect of deprecated site local addresses on router renumbering (rfc 2894)

Hi All,

RFC 2894 ' Router Renumbering for IPv6'describes the Renumbering of
Prefixes using RR commands to multicast addresses. (Site local OR Link
local).

Since the site local addresses are now deprecated (RFC 3879), we can
assume that RR is now supported only for Link local addresses (unicast
and multicast).

What is the relevance of the 'S'(site specific) flag now in the command
message. Should the 'S' flag be evaluated even if the scope of
destination address is Link local (unicast or multicast)?

Since RFC 2894 says that the 'S' flag should be ignored unless the
router treats interfaces as belonging to different "sites", in this case
should the RR command messages be limited only to the interfaces on that
link OR to all interfaces on the router?

Thanks and Regards,
Suraj.
