ipv6 nd prefix (DHCPv6)
Overview Use this command to specify IPv6 RA (Router Advertisement) prefix information
generated from the DHCPv6 server for DHCPv6 prefix-delegation for a VLAN.
Use the no variant of this command to remove IPv6 RA prefix information from the
DHCPv6 Server for DHCPv6 Prefix-Delegation for the interface. Use the all
parameter with the no variant of this command to remove all prefix names and all
prefixes for an interface.
Syntax
ipv6 nd prefix <ipv6-prefix-name>
<ipv6-prefix/length>{<valid-lifetime>|infinite}
{<preferred-lifetime>|infinite} {off-link|no-autoconfig}
no ipv6 nd prefix {<ipv6-prefix-name>|<ipv6-prefix/length>|all}
Parameter Description
<ipv6-prefix-
name>
The IPv6 prefix name advertised on the router advertisement
message sent from the device.
The IPv6 prefix name is delegated from the DHCPv6 Server
configured for DHCPv6 Prefix-Delegation.
<ipv6-prefix/
length>
The IPv6 prefix and prefix length advertised on the router
advertisement message sent from the device.
The IPv6 address prefix uses the format X:X::/prefix-length. The
prefix-length is usually set between 0 and 64. .
<valid-
lifetime>
The the period during which the specified IPv6 address prefix is
valid. This can be set to a value between 5 and 315360000 seconds.
Note that this period should be set to a value greater than that set
for the prefix preferred-lifetime. See the Usage notes after this
parameter table for a description of valid lifetime and how it
determines invalid IPv6 addresses upon expiry.
infinite Specifying this keyword instead of entering a value for the
<valid-lifetime> parameter applies an infinite valid lifetime.
<preferred-
lifetime>
Specifies the IPv6 prefix preferred lifetime. This is the period during
which the IPv6 address prefix is considered current. Set this to a
value between 0 and 315360000 seconds.
Note that this period should be set to a value less than that set for
the prefix valid-lifetime. See the Usage notes after this parameter
table for a description of preferred lifetime and how it determines
deprecated IPv6 addresses upon expiry.
infinite Specifying this keyword instead of entering a value for the
<preferred-lifetime> parameter applies an infinite valid lifetime.
off-link Specify the IPv6 prefix off-link flag.
no-autoconfig Specify the IPv6 prefix no autoconfiguration flag. Setting this flag
indicates that the prefix is not to be used for autoconfiguration.
all Specify all prefix names and all prefixes are removed when used
