ifdefault

Specifies the router behavior for all interfaces. Use the following syntax to set router parameters and corresponding values: 

ifdefault [variable-value]

prefixdefault

Specifies the default behavior for prefix advertisements. Use the following syntax to set router parameters and corresponding values: 

prefixdefault [variable-value]

if

Sets per-interface parameters. Use the following syntax: 

if interface [variable-value]

prefix

Advertises per-interface prefix information. Use the following syntax: 

prefix prefix/length interface [variable-value]

AdvRetransTimer

0 

Specifies the value in the Retrans Timer field in the advertisement messages sent by the router. 

AdvCurHopLimit

Current diameter of the Internet 

Specifies the value to be placed in the current hop limit in the advertisement messages sent by the router. 

AdvDefaultLifetime

3 + MaxRtrAdvInterval

Specifies the default lifetime of the router advertisements. 

AdvLinkMTU

0 

Specifies a maximum transmission unit (MTU) value to be sent by the router. The zero indicates that the router does not specify MTU options. 

AdvManaged Flag

False 

Indicates the value to be placed in the Manage Address Configuration flag in the router advertisement. 

AdvOtherConfigFlag

False 

Indicates the value to be placed in the Other Stateful Configuration flag in the router advertisement. 

AdvReachableTime

0 

Specifies the value in the Reachable Time field in the advertisement messages sent by the router. 

AdvSendAdvertisements

False 

Indicates whether the node should send out advertisements and respond to router solicitations. You need to explicitly set this variable to “TRUE” in the ndpd.conf file to turn on router advertisement functions. For more information, refer to How to Configure an IPv6-Enabled Router.

DupAddrDetect

Transmits

1 

Defines the number of consecutive neighbor solicitation messages that the Neighbor Discovery protocol should send during duplicate address detection of the local node's address. 

MaxRtrAdvInterval

600 seconds 

Specifies the maximum time to wait between sending unsolicited multicast advertisements. 

MinRtrAdvInterval

200 seconds 

Specifies the minimum time to wait between sending unsolicited multicast advertisements. 

StatelessAddrConf

True 

Controls whether the node configures its IPv6 address through stateless address autoconfiguration. If False is declared in ndpd.conf, then the address must be manually configured. For more information, refer to How to Configure a User-Specified IPv6 Token.

TmpAddrsEnabled

False 

Indicates whether a temporary address should be created for all interfaces or for a particular interface of a node. For more information, refer to How to Configure a Temporary Address.

TmpMaxDesyncFactor

600 seconds 

Specifies a random value to be subtracted from the preferred lifetime variable TmpPreferredLifetime when in.ndpd starts. The purpose of the TmpMaxDesyncFactor variable is to prevent all the systems on your network from regenerating their temporary addresses at the same time. TmpMaxDesyncFactor allows you to change the upper bound on that random value.

TmpPreferredLifetime

False 

Sets the preferred lifetime of a temporary address. For more information, refer to How to Configure a Temporary Address.

TmpRegenAdvance

False 

Specifies the lead time in advance of address deprecation for a temporary address. For more information, refer to How to Configure a Temporary Address.

TmpValidLifetime

False 

Sets the valid lifetime for a temporary address. For more information, refer to How to Configure a Temporary Address.

AdvAutonomousFlag

True 

Specifies the value to be placed in the Autonomous Flag field in the Prefix Information option.  

AdvOnLinkFlag

True 

Specifies the value to be placed in the on-link flag (“L-bit”) in the Prefix Information option. 

AdvPreferredExpiration

Not set 

Specifies the preferred expiration date of the prefix. 

AdvPreferredLifetime

604800 seconds 

Specifies the value to be placed in the preferred lifetime in the Prefix Information option.  

AdvValidExpiration

Not set 

Specifies the valid expiration date of the prefix. 

AdvValidLifetime

2592000 seconds 

Specifies the valid lifetime of the prefix that is being configured.
