    Associating the Shared IPv6 Interface with the Layer 2 Interface

    You can specify the layer 2 interface used by a shared IPv6 interface. The command fails if the layer 2 interface does not yet exist. The command is not supported (that is, it fails) if you use an RSVP tunnel (for example, tunnel mpls:1) to identify the layer 2 interface.

    After creating the shared IPv6 interface, you can configure it as you do any other IPv6 interface. The shared interface is operationally up when the layer 2 interface is operationally up. You can create operational shared IPv6 interfaces in the absence of a primary IPv6 interface.

    To associate a shared IPv6 interface with a layer 2 interface:

    • Issue the ipv6 share-interface command in Interface Configuration mode.
      host1(config-if)#ipv6 share-interface atm 5/3.101

      Use the no version to remove the association between the layer 2 interface and the shared IPv6 interface. You can delete shared and primary IPv6 interfaces independently.
