[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] ipv6 address auto
With stateless IPv6 address autoconfiguration enabled, but no IPv6 address configured for
VLAN-interface 2, Switch A automatically generates a link local address. It sends an RS message
to Switch B to request configuration information for IPv6 address generation. Upon receiving the
RS message, Switch B sends back an RA message. After receiving an RA message with the M flag
set to 0 and the O flag set to 1, Switch A performs stateless DHCPv6 to get other configuration
parameters.
