So my proposal would be to add an option to RA. This option specifies a time over which nodes should distrubute updating the router (random number between zero and the timeout). At the selected time, the node then starts NUD on the router. Note that it has to do that for all of its addresses. Which is not part of ND at the moment. This should be enough. When a node boots it sends an RS. When a node adds a new address (not triggered by an RA) it may need to go over its list of routers and update them. Routers can always add the option to their RAs. But an alternative is to do that only when they become overloaded. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
