* NACR FYI: Fake ASs

["Steven J. Richardson" <sjr () merit edu>]

Dear Regional Techs:

  As has been announced in the "Additions to the NSFNET policy-based
routing database" messages, we now are in a position where we have to
use:

        <metric>:<AS>(<NSS>) 

in the "aslist" of NACRs, due to the removal of "fake" ASs for Alternet,
CA*net, DSI, ESnet.

  The change affects NACRs which you would have submitted with aslists
containg these ASs: 

        60 or 274 (DSI)
        291, 293 (ESnet)
        601, 602, 603 (CA*net)
        701, 702 (Alternet)

The following table shows which ASs correspond to the above ASs, and how
the AS should be identified in aslists in NACRs (and in Merit reports):

        Old AS                  New AS  in aslist
        ======                  ======  =========
        60                      2699    2699(144)
        274                     2699    2699(145)

        291                     293     293(144)
        293                     293     293(145)

        601                     577     577(133)
        602                     577     577(143)
        603                     577     577(137)
        
        701                     701     701(136)
        702                     701     701(134)

[In the very near future, we will also have BARRnet set up this way:

        200                     200     200(128)
        201                     200     200(144)

Until we notify this list, please continue to use ASs 200 and 201.]


  Thanks for your help,


  Steve Richardson/Merit
