ipv6 nd autoconfig other-flag

Function

The ipv6 nd autoconfig other-flag command sets the "other configuration" flag (O flag) in the RA message, indicating whether hosts should use stateful autoconfiguration to obtain additional information (excluding addresses).

The undo ipv6 nd autoconfig other-flag command clears the "other configuration" flag (O flag) set in the RA message.

By default, the "other configuration" flag (O flag) is not set in the RA message.

Usage Guidelines

Usage Scenario

If the O flag is set, the attached hosts should use stateful autoconfiguration to obtain additional configuration information (excluding IPv6 addresses). Additional configuration information includes the router lifetime, neighbor reachable time, retransmission interval, and PMTU.
If the O flag is not set, the attached hosts should use stateless autoconfiguration to obtain additional configuration information. That is, the attached hosts obtain additional configuration information through the RA messages advertised by Routers.

Prerequisites

IPv6 has been enabled on the involved interface using the ipv6 enable command.

Configuration Impact

If the ipv6 nd autoconfig managed-address-flag command is run, hosts can obtain additional configuration information (excluding IPv6 addresses) though the ipv6 nd autoconfig other-flag command is not run.

To check whether the attached hosts obtain IPv6 addresses through stateful autoconfiguration or stateless autoconfiguration, run the display ipv6 interface command.

Precautions

The interface on a Router cannot use stateful and stateless address autoconfiguration simultaneously to obtain additional configuration information (excluding IPv6 addresses).

Example

# Set the "other configuration" flag (O flag) on GE 0/1/1.
