The Router Advertisement Daemon Configuration File: /etc/rtradvd.conf
The HP-UX IPv6 Router Advertisement Daemon configuration file, /etc/rtradvd.conf by default, contains
parameters that determine how the system constructs the IPv6 Router Advertisement messages it sends.
Specifically for Mobile IPv6, the rtradvd configuration file determines if a system is Home Agent—not the
mip6mod configuration file.
The following is a list and description of the Mobile IPv6-related configuration parameters you can configure
in the rtradvd configuration file:
NOTE Use the man rtradvd.conf command to view the rtradvd configuration file (4) manpage.
AdvHomeAgentFlag [on | off]
Enables (on), or, disables (off), the system as a Home Agent on the link. If
AdvHomeAgentFlag is on, the rtradvd sets the Home Agent flag in the Router
Advertisement messages it sends. You can also use the extended minimum values for the
rtradvd MinRtrAdvInterval and MaxRtrAdvInterval parameters when
AdvHomeAgentFlag is on. The MinRtrAdvInterval and MaxRtrAdvInterval parameters
determine the rate at which the rtradvd sends unsolicited Router Advertisement messages.
The default value for AdvHomeAgentFlag is: off
AdvHomeAgentLifetime [integer]
Specifies the lifetime (in seconds) of the system as a Home Agent. The
AdvHomeAgentLifetime value must be in the range [1–65,520]. Note: 65,520 seconds is 18.2
hours.
The default value for AdvHomeAgentLifetime is the value of the AdvRouterLifetime
parameter.
AdvHomeAgentPreference [integer]
Specifies a preference level for the system to serve as a Home Agent. Higher values indicate
serving as a Home Agent is preferable. You must also set the AdvHomeAgentLifetime
parameter. If either the AdvHomeAgentPreference and AdvHomeAgentLifetime are set to
their default values, the Home Agent information will not be included in Router
Advertisement messages sent by the system when it is a Home Agent.
The default value for AdvHomeAgentPreference is: 0
AdvIntervalOpt [on | off]
Enables (on), or, disables (off), the inclusion of the Advertisement Interval Option in Router
Advertisement messages. Enabling the parameter and the Advertisement Interval Option
allows you to use the Mobile IPv6 minimum limits for the rtradvd MinRtrAdvInterval and
MaxRtrAdvInterval parameters.
The default value for AdvIntervalOpt is: off
AdvRouterAddress [on | off]
Enables (on), or, disables (off), the setting of the Router Flag field in the Prefix Information
option. Enabling this parameter and the Prefix Information option will include the complete
IP address of the sending router in the Prefix field of the Router Advertisements it sends.
The default value for AdvRouterAddress is: off
MaxRtrAdvInterval [integer]
Specifies the maximum time interval (in seconds) between unsolicited multicast Router
Advertisements sent from the interface. When using Mobile IPv6, the MaxRtrAdvInterval
value must be in the range [.07–1800] seconds.
