IPv6 Neighbor Discovery Prefix Options (continued)
Command Syntax and Usage
no ipv6 nd prefix {<IPv6 prefix> <IPv6 prefix length>|interface
<IP interface number>|all}
Removes a Neighbor Discovery prefix. If you specify an interface number, all
prefixes for the interface are removed.
Command mode: Interface IP
ipv6 nd prefix <IPv6 prefix> <IPv6 prefix length> no­autoconfig
Disables the autonomous flag. When enabled, the autonomous flag indicates
that the prefix can be used for stateless address configuration.
The default setting is enabled.
Command mode: Interface IP
ipv6 nd prefix <IPv6 prefix> <IPv6 prefix length> off­link
Disables the on‐link flag. When enabled, the on‐link flag indicates that this
prefix can be used for on‐link determination. When disabled, the
advertisement makes no statement about on‐link or off‐link properties of the
prefix.
The default setting is enabled.
To clear the off‐link flag, omit the off‐link parameter when you issue this
command.
Command mode: Interface IP
ipv6 nd prefix <IPv6 prefix> <IPv6 prefix length> valid­lifetime
{<0‐4294967295>|infinite|variable <0‐4294967295>}
[prefered­lifetime {<0‐4294967295>|infinite|variable}]
[no­autoconfig] [off­link]
Configures the Valid Lifetime and (optionally) the Preferred Lifetime of the
prefix, in seconds.
The Valid Lifetime is the length of time (relative to the time the packet is sent)
that the prefix is valid for the purpose of on‐link determination.
The default value is 2592000.
The Preferred Lifetime is the length of time (relative to the time the packet is
sent) that addresses generated from the prefix via stateless address
autoconfiguration remain preferred.
The default value is 604800.
Note: The Preferred Lifetime value must not exceed the Valid Lifetime value.
Command mode: Interface IP
show ipv6 prefix <IP interface number>
Displays current Neighbor Discovery prefix parameters.
Command mode: All
