icmpV6OptionPrefixInformation

icmpV6OptionPrefixInformation - configures the icmpV6 Prefix Information option.

SYNOPSIS

icmpV6OptionPrefixInformation sub-command options

DESCRIPTION

The icmpV6OptionPrefixInformation command is used to configure the icmpV6 Prefix Information option.

This option can be used in all Neighbor Discovery messages:

STANDARD OPTIONS

 

type

Read-only. The value for this option = 3.

length

The length of the option. One unit of length = 8 octets. (default = 1)

A length value = 0 is invalid, and the node MUST silently discard a Neighbor Discovery packet where length = 0.

prefixLength

Configures the prefix length. The number of valid bits in the prefix. (default = 0)

enableLinkFlag
true/false

If enabled, this prefix can be used for determining if the prefix is on-link. (default = false)

enableAutonomous AddressConfig
true/false

If enabled, this prefix can be used for autonomous address configuration. (default = false)

enableRouterAddress
true/false

If enabled, indicates a router. The prefix option should not be sent by a router for a link-local prefix. (default = false)

enableSitePrefix
true/false

If enabled, indicates a host/site. The prefix option should be ignored by a host, for a link-local prefix. (default = false)

validLifetime

(32-bit integer) The time, starting from packet transmission, that the prefix is valid-in seconds. (0xffffffff = infinity.) (default = 0)

preferredLifetime

(32-bit integer) The time, starting from packet transmission, that the addresses generated from the prefix are "preferred"-in seconds. (0xffffffff = infinity.) (default = 0)

prefix

Can be an IPv6 address or an IPv6 address prefix. The valid leading bits are specified by the setting in the "prefixLength" field. All following bits MUST be set to zero by the sending node and are ignored upon receipt.
(default = '0:0:0:0:0:0:0:0')

COMMANDS

The icmpV6OptionPrefixInformation command is invoked with the following sub-commands. If no sub-command is specified, returns a list of all sub-commands available.

icmpV6OptionPrefixInformation setDefault

Sets to IxTclHal default values for all configuration options.

EXAMPLES

See example under icmpV6.
