    When an IPv6 is connected to this network with the address configured via auto config, it will not select an address covered by this prefix.

    configure a router attached to this subnet to check this out  - make sure that port fast is enabled on the switchport attached to the router.

    as I understand from you that this command: ipv6 nd prefix fc00:1:1:58::/64 14400 14400 no-autoconfig

     

    will advertise this prefix to all nodes except for those who are enabled with ipv6 address autoconfig

     

    right !?

    right !?

    Wrong

    All nodes will see this advertisement, however those negotiating an address via autoconfig will not be able to take an address from this prefix!
