Parameters
None
Description
Use the ipv6 nd autoconfig other-flag command to set the other stateful configuration flag (O) flag to
1 so that the host can acquire information other than IPv6 address through stateful autoconfiguration
(for example, DHCP server).
Use the undo ipv6 nd autoconfig other-flag command to restore the default.
By default, the O flag is set to 0 so that the host can acquire other information through stateless
autoconfiguration.

autoconfiguration.
