TN(or X) NUT ------------------------------ Initialize NUT (see INITIALIZATION)
Configure address of NUT (addrconf=manual+_GLOBAL0A0N_UCAST, see Addrconf phase)
TN wait the DAD NS sends from NUT <=== Judgement #1: DAD NS ==== name: dadns_from_NUT
Immediately (within $RetransTimerSec [sec]) send DAD Packet to force NUT to detect address duplication. ==== Action #1: DAD NS ====> name: dadpkt_to_NUT
Wait for NUT to finish DAD. (sleep $RetransTimerSec [sec])
Check if NUT's address is not configured ==== Action #2: DAD NS ====> name: chkconf_dadns_to_NUT
DAD NA does not come because NUT detect address duplicated and address is not configured. <=== Judgement #2: DAD NA does not come==== name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router)
Judgement #1. DAD NS must come from NUT on Manual Global address configuration. name: dadns_from_NUT src: ::0 dst: solnode[NUT's tentative _GLOBAL0A0N_UCAST_ADDR] TargetAddress: NUT's tentative _GLOBAL0A0N_UCAST_ADDR
Action #1. Send DAD NA to force NUT to detect address duplication. name: dadpkt_to_NUT ether src: the same as NUT's MAC address src: NUT's tentative _GLOBAL0A0N_UCAST_ADDR dst: allnodes multicast TargetAddress: NUT's tentative _GLOBAL0A0N_UCAST_ADDR
Action #2. Send DAD NS to check if NUT's address is not configured name: chkconf_dadns_to_NUT src: ::0 dst: solnode[NUT's _GLOBAL0A0N_UCAST_ADDR] TargetAddress: NUT's _GLOBAL0A0N_UCAST_ADDR
Judgement #2. DAD NA must not come from NUT because NUT detect address duplication. name: chkconf_dadna_from_NUT (or chkconf_dadna_from_NUT_rf1 if NUT is a Router) src: NUT's Link-local address or _GLOBAL0A0N_UCAST_ADDR dst: allnodes multicast TargetAddress: NUT's _GLOBAL0A0N_UCAST_ADDR OFlag: 1 RFlag: 0 ( if NUT is a Router then 1)
