The original intent in the scoped addr arch was that the site-local
zone id would be indicate which interfaces are within a site. The
filtering between sites is handled by the forwarding code.
Vendors that support these zone ids will have default values for the
zone ids. If the vendors don't support the zone ids, the box will
be unable to act as a SBR unless the user builds the filters.
"default value for zone ids"? which document suggests that?
i have never seen such docs. draft-ietf-ipngwg-scoping-arch-04.txt
talks about default zone id for global address (= 0), but is silent
about site-locals to me.

From Section 6:
An implementation should also support the concept of a "default" zone
for each scope. It is convenient to reserve the index value zero, at
each scope, to mean "use the default zone". Unlike other zone
indices, the default ID does not contain any scope type, and the
scope type is determined by the address by which the default ID was
accompanied. An implementation may additionally define a separate
default zone for each scope type. Those default indices can also be
used as the zone qualifier for an address for which the node is
attached to only one zone, e.g., when using global addresses.
