(Optional) Configuring Forwarding Isolation Between AC Interfaces

(Optional) Configuring Forwarding Isolation Between AC Interfaces


If multiple users are bound to the same VSI, you can use the isolate spoken command to enable forwarding isolation between AC interfaces. After this command is run, the VSI attribute of all AC interfaces in the VSI is spoke, preventing the users from communicating with each other.

Before configuring forwarding isolation between AC interfaces, the VPLS signaling configuration must have been completed.
  • For Martini VPLS, the pwsignal ldp and vsi-id vsi-id commands have been run.

  • For Kompella VPLS, the pwsignal bgp and route-distinguisher route-distinguisher commands have been run.

  • For BGP AD VPLS, the bgp-ad and vpls-id vpls-id commands have been run.


Only the X series cards support this function.

    The system view is displayed.

  2. Run vsi vsi-name

    The VSI view is displayed.

  3. Run isolate spoken

    By default, forwarding isolation between AC interfaces in a VSI is disabled.

  4. Run quit

  5. (Optional) If one AC interface wants to communicate with other AC interfaces in the same VSI, set the VSI attribute of this AC interface to hub.
    1. Run interface interface-type interface-number

      The AC interface view is displayed.

    2. Run hub-mode enable
