I am looking for the actual Pseudo-MAC addresses for a TP4 imnplementation for the ES.IS-ES Group Multicast and the ES.IS-IS Group Multicast. I understand that there was a TOP/NetBIOS discussion that got blessed by the NIST on this regard, but have yet to find any paper documention on this subject. I need help! Here is what I found: IS-ES: 09002b000004 but my router thinks differently! I found it wants: IS-ES: 030000000200 (cisco...) Has there been an addendum or change to the 1988 NIST agreement? IS cisco wrong on this matter? I can edit the initialization tables to conform to cisco's router, but am concerned that this will preclude my ability to connect to a multi-vendor OSI/NetBIOS network...yes? -- +--------------------------------------------------------------------------+ | Carlo Milono: cmilono@netcom.apple.com or apple!netcom!cmilono | |"When a true genius appears in the world, you may know him by this sign, | |that the dunces are all in confederacy against him." - Jonathan Swift | +--------------------------------------------------------------------------+

I found references to the addresses in: 1988 NIST agreement (which reversed IS and ES addresses) AT&T documentation (the addresses for csma come from their bank of numbers) TOP/NetBIOS Working Group of the MAP/TOP committee Basically, 'cisco' made a boo-boo in several ways: 1) all standards related to these addresses state that they must be CONFIGURABLE (PROMS do *not* count!) 2) in some cases, the 4th and 5th octets were reversed - in others it is inexplicable where they got the numbers..... A fix is on the way (OH, how I wish I didn't have to deal with TR!). -- +--------------------------------------------------------------------------+ | Carlo Milono | | Personal: cmilono@netcom.com or apple!netcom!cmilono | | Hobbes: "Life in the Great Suburban Outback is certainly fraught with | | peril." | | Calvin: "If you'd seen it, you'd have been scared too." | +--------------------------------------------------------------------------+

NIST Stable Implementation Agreements Ver.2 Ed.4 agrees... ALL-ES= 09 00 2B 00 00 04 ALL-IS= 09 00 2b 00 00 05 Our Cisco MGS uses these addresses also. Steve Russert .

HELP! I was the original poster of the NSAP thread. I have gotten many responses, but I finally got one that has me very, very confused. It seems that the CSMA ES and IS addresses have been stable for some time; however, I am dealing with Token Ring and thought I had the problem licked until today. Here are the addresses in question - but there is a *new* standard that has yet to be logged as official...and the addresses have changed! 802.5 ESIS_ES ES address c0.00.00.08.00.00 03.00.00.10.00.00 NIST 1988, MAP/TOP, three vendors c0.00.00.00.40.00 NIST 1990 OSI Workshop (draft???) and cisco 03.00.00.00.02.00 802.5 ESIS_IS IS address c0.00.00.10.00.00 03.00.00.08.00.00 NIST 1988, MAP/TOP, three vendors c0.00.00.00.80.00 03.00.00.00.01.00 NIST 1990 OSI Workshop (draft???) and cisco I also understand that there are other standards bodies involved in Europe that adhere to the NIST 1988 and MAP/TOP agreements...and that the 1990 Workshop stuff is not yet written into the books. Where can I FTP a copy of both the 1988 NIST and 1990 NIST documents...why change addresses? I understand using the least-significant-bit of the MSByte - but these changes/differences are 'in the middle' of the address. Oh, help. Oh, help. -- +--------------------------------------------------------------------------+ | Carlo Milono | | Personal: cmilono@netcom.com or apple!netcom!cmilono | | Hobbes: "Life in the Great Suburban Outback is certainly fraught with | | peril." | | Calvin: "If you'd seen it, you'd have been scared too." | +--------------------------------------------------------------------------+
