* NACR FYI: Fake ASs

Thu May 26 16:46:40 UTC 1994

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
