Data Requirements

**Table 3** Configuring ND data on an interface
Item	Data	Description
Enabling the function that sends RA messages	send-advertisements	Enable the function that sends RA messages.
Configuring the maximum interval for sending RA messages	max-rtr-adv-interval	Configure the maximum interval for sending RA messages.
Configuring the minimum interval for sending RA messages	min-rtr-adv-interval	Configure the minimum interval for sending RA messages.
Configuring the M flag of stateful address autoconfiguration in an RA message	managed-flag	Configure the M flag of stateful address autoconfiguration in an RA message.
Configuring the other-config flag of stateful address autoconfiguration in an RA message	other-config-flag	Configure the other-config flag of stateful address autoconfiguration in an RA message.
Configuring the IPv6 neighbor reachable time	reachable-time	Configure the IPv6 neighbor reachable time.
Configuring the interval for sending Neighbor Solicitation (NS) messages	retrans-timer	Configure the interval for sending NS messages.
Configuring the hop limit of RA messages	cur-hop-limit	Configure the hop limit of RA messages.
Configuring the lifetime of RA messages	default-lifetime	Configure the lifetime of RA messages.
Configuring RA messages not to carry the default prefix generated by an interface IPv6 address	no-advertise	Configure RA messages not to carry the default prefix generated by an interface IPv6 address.
Configuring the valid lifetime of prefixes	valid-lifetime	Configure the valid lifetime of prefixes.
Configuring the O-Flag	on-link-flag	Configure the O-Flag. If this parameter is specified, the prefix carried in the RA message cannot be allocated to the local link.
Configuring the preferred lifetime of prefixes	preferred-lifetime	Configure the preferred lifetime of prefixes. The preferred lifetime cannot be larger than the valid lifetime.
Removing the A-Flag	autonomous-flag	Remove the A-Flag. If this parameter is specified, the configured prefix cannot be used in stateless address auto-configuration. The A-Flag indicates the autonomous address configuration in the prefix option of RA messages.
