What address autoconfiguration is
IPv6 defines both a stateful and a stateless address autoconfiguration mechanism. Data ONTAP 7.3.1 onwards supports IPv6 stateless address autoconfiguration. The Neighbor Discovery protocol facilitates address autoconfiguration.
- What stateless address autoconfiguration is
The stateless address autoconfiguration mechanism allows a host to generate its own addresses by using a combination of locally available information and router-advertised information. The stateless address autoconfiguration requires minimal manual configuration of hosts and routers.
- Enabling or disabling router-advertised messages
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.
