Have you enabled 'ipv6 unicast-routing' enabled in the global config mode?

HTH, Gustavo

Thank you for your reply and I can not open the link because of Forbidden.

I type the command ipv6 unicasting but it can not.

Wonderful, after i configure command

Switch(config)#sdm prefer dual-ipv4-and-ipv6 default

i can use IPv6 features.

Thank, Andre.

Why we need to configure this command for the switch?

Any special reason?
