# Enable stateless IPv6 address autoconfiguration on GigabitEthernet 0/1.
[Device] interface gigabitethernet 0/1
[Device -GigabitEthernet0/1] ipv6 address auto
With this command executed, if GigabitEthernet 0/1 has no IPv6 address configured, the device will
automatically generate a link-local address, and send a router solicitation (RS) message, requesting the
gateway (the router) to reply with an RA message immediately.
Verification
After receiving an RA message with the M flag set to 0 and the O flag set to 1, the device automatically
enables stateless DHCPv6.
