Both setting the trigger of re-request on renumbering of prefix in RA, and a multicast Reconfigure message might cause all nodes to rush on the single DHCPv6-lite server for information-request reply exchange. It could work with small number of clients though. Periodical information-request from client side as Ralph suggested, and multicast advertisement of DNS option itself (w/ DHCPv6-lite, RA, SLP) seems to work with large number of clients. -- SHIRASAKI Yasuhiro #---------------------------------------------------------------------- # To unsubscribe, send a message to <dnsop-request@cafax.se>.
