-----Summary-----

Per the SIX "Switch Interconnection Policy" ...

  - "Members may only utilize a single layer-2 MAC address to place a 
    single layer-3 router per port allocated from the SIX switch fabric 
    unless by prior agreement of the board. The procedure for 
    interconnecting a layer-2 device to the SIX shall be as follows: a 
    technical proposal shall be made to the board, accompanied by full 
    documentation. This documentation shall be published on the 
    announcement mailing list and the SIX web site for comment by the 
    members and the public for a period of no less than two weeks, 
    whereupon the board shall determine whether the operator is allowed to 
    perform the proposed interconnection. No more than one such proposal 
    shall be entertained at a time, and any subsequent modifications to 
    the interconnected equipment shall be similarly approved by the board. 
    The operator shall be responsible for maintaining any required 
    documentation of all layer-2 devices comprising the switch fabric, and 
    such documentation shall always be available to SIX operations 
    volunteers."

... Altopia is seeking permission to allow a second layer-2 MAC address on 
its connection to the SIX. The second layer-2 MAC will be used for a 
second Altopia router.

-----Physical Information-----

- Design: The existing Altopia SIX connection terminates layer-3 on a 
  router.  With permission, the SIX connection will be moved to a switch 
  so that it can be accessed by two Altopia (AS 6456) routers.  No further 
  layer-2 devices will be connected.

- Comments:  This switch will not operate as an extension switch beyond 
  connecting a second Altopia router.
