    Enabling or Disabling an IPv6 Interface

    You can enable or disable an IPv6 interface at any time.

    Note:

    • Before you configure IPv6, you must create the lower-layer interfaces over which IPv6 traffic flows.
    • By default, an IPv6 interface is enabled when you first create it.

    To enable an IPv6 interface:

    • Issue the ipv6 enable command in Interface Configuration mode.
      host1(config-if)#ipv6 enable

      Use the no version to disable IPv6 on an interface or a subinterface.
