length
TheIPv6networkprefixandtheprefixlengthbeingconfigured.
TheprefixmustbeintheformdocumentedinRFC4291,withthe
addressspecifiedinhexadecimalusing16‐bitvaluesbetweencolons.
Theprefixlengthisadecimalnumberindicatingthe
numberofhigh‐
ordercontiguousbitsoftheaddressthatcomprisethenetworkportion
oftheaddress.
valid‐lifetime|infinite (Optional)Specifiesthelengthoftimeinseconds(relativetothetime
thepacketissent)thattheprefixisvalidforthepurposeofon‐link
determination.
Thelifetimevalue
canrangefrom0to4,294,967,295.
Specifyinginfinitemeansthattheprefixisalwaysvalid.
preferred‐lifetime|
infinite
(Optional)Specifiesthelengthoftimeinseconds(relativetothetime
thepacketissent)thataddressesgeneratedfromtheprefixby meansof

Thelifetimevalue
canrangefrom0to4,294,967,295.
Specifyinginfinitemeansthattheprefixisalwayspreferred.
no‐autoconfig Unsetstheautonomousaddress‐configurationflag.Whennotset,
meansthatthisprefixcannotbeusedforautonomousaddress
configuration.Bydefault,theautonomousaddress‐configurationflagis
set/enabled.
off‐link Unsetstheon‐linkflag.
Whennotset,meansthatthisprefixcannotbe
usedforon‐linkdetermination.Bydefault,theon‐linkflagisset/
enabled.
