You can specify prefixes in the router advertisement messages as autonomous. When set as autonomous, the prefixes are used for stateless address autoconfiguration. By default, prefixes are autonomous.
To explicitly specify prefixes as autonomous, include the autonomous statement:
-
autonomous;
To specify prefixes as not autonomous, include the no-autonomous statement:
-
no-autonomous;
For a list of hierarchy levels at which you can configure these statements, see the statement summary sections for these statements.
