You can use the ip.v6.ra_enable option to enable or disable router-advertised (RA) messages. RA messages help in autoconfiguring addresses that have global scope and in learning routes and prefixes. If, due to security reasons, you do not want the MAC address of the network interfaces to be viewed by any external network, you can disable RA address autoconfiguration.
Considerations
- By default, the ip.v6.ra_enable option
is set to on.
- You can enable the RA option
only for the entire storage system; you cannot enable it for a network interface.
- Disabling the RA option does not remove the existing autoconfigured addresses and the routes
learned.
- When the RA option is disabled, the RA message is
dropped. Therefore, no default route is learned, the default router
failover is disabled, and link MTU updates are stopped.
Step
- To enable or disable RA address autoconfiguration, enter the following command: options ip.v6.ra_enable {on|off}
on—Enables RA address autoconfiguration.
off—Disables RA address autoconfiguration.
