Greetings, RFC 3484 section 3.1 defines "subnet-local (0x03)" multicast scope, but later RFC 4291 section 2.7 defines this multicast scope value as reserved. Can I ask if the later interpretation is the correct one?
I ask in the context of e.g. http://tools.ietf.org/html/draft-lynn-homenet-site-mdns where we need a scope greater than link-local in order to span a 6LoWPAN subnet, but less than site-local in order to reserve the property "Each interface belongs to exactly one zone of each possible scope." for future site-local protocols that might include the 6LoWPAN router port. Should I select admin-local scope, or is subnet-local scope available for use? Thanks, -K-
