Are you talking about multicast group addresses? They are a perfect example of a forwarding selector. At each hop, forwarding uses them to decide on a next-hop, but they do not name a particular point of attachment. Just because they are not 'locators' doesn't mean they are identifiers. What was it Noel said about trying to fit everything into too few names? _______________________________________________ rrg mailing list [email protected] http://www.irtf.org/mailman/listinfo/rrg
