•
If the M flag is set to 0 in RA advertisements, receiving hosts use stateless autoconfiguration.
Stateless autoconfiguration generates IPv6 addresses according to link-layer addresses and
the prefix information in the RA advertisements.
Examples
# Set the M flag to 1 in RA advertisements to be sent.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd autoconfig managed-address-flag
ipv6 nd autoconfig other-flag
Use ipv6 nd autoconfig other-flag to set the other stateful configuration flag (O) to 1 in RA
advertisements to be sent.
Use undo ipv6 nd autoconfig other-flag to restore the default.
Syntax
ipv6 nd autoconfig other-flag
undo ipv6 nd autoconfig other-flag
Default
The O flag is set to 0 in RA advertisements. Hosts receiving the advertisements will acquire other
information through stateless autoconfiguration.

Usage guidelines
The O flag in RA advertisements determines whether receiving hosts use stateful autoconfiguration
to obtain configuration information other than IPv6 addresses.
•
If the O flag is set to 1 in RA advertisements, receiving hosts use stateful autoconfiguration (for
example, from a DHCPv6 server) to obtain configuration information other than IPv6
addresses.
•
If the O flag is set to 0 in RA advertisements, receiving hosts use stateless autoconfiguration to
obtain configuration information other than IPv6 addresses.
Examples
# Set the O flag to 0 in RA advertisements to be sent.
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] undo ipv6 nd autoconfig other-flag
ipv6 nd dad attempts
Use ipv6 nd dad attempts to set the number of attempts to send an NS message for DAD.
Use undo ipv6 nd dad attempts to restore the default.
Syntax
