Hi Geoff, As far as I understand: 1 if a standard 4861 node (node A here) joins a lowpan with lowpan ND. Node B is a node using 6lowpan ND - DAD will fail (nobody answers to NS) - Address resolution will fail (same) - NUD fails (same) - if the router does not also send standard Prefix Information Option in Ras (but only 6lowpan information option), -- prefix discovery fails (incl on-link prefixes) -- autoconfiguration fails
Regarding node B: - If node A does not respect the binding between its L3 and L2 address, (the assumption that the IPv6 suffix is based on the MAC, for instance if node A uses DHCP or CGA), node B will not be able to contact node A - the white board is not authoritative anymore (A does not register), - hence DAD fails for node B. 2 Now for a node using 6lowpan ND only in a pure 4861 network: - DAD will fail (the node does not send NS) - Address resolution will fail (same) - NUD fails (same) - prefix discovery, autoconfiguration fails (no 6lowpan Information Option in RA) - This node will just not work at all, but will not disturb other nodes. This might be a real issue.
