"Helps"? Doesn't the flow label tell the router exactly which instance to use? > It does not help a host that needs to select a router that serves that > instance. The trouble I have with this is that "select a router" sounds a lot like routing. We already have a mechanism for selecting which router to send a packet to: DIOs. If a device wants to select between next hops based on routing metrics then it should be a router. Why is this such a burden? Listening to DIOs and making routing decisions based on them does not require sending DIOs or forwarding packets for others. [Mathilde] What you are describing looks like a RPL leaf node but does not really need the IPv6 router functionalities i.e. forwarding, sending RA, etc. This is exactly what I was trying to point out when I was asking if a RPL leaf node could be an IPv6 host... Best, Mathilde
