As pointed out to me by Ytti I was doing interface authentication and you are doing LSP autentication. I changed my lab and got the following debug from debug isis update-packets:
ISIS-Upd: Rec L1 LSP 0000.0000.0002.00-00, seq 4, ht 1199, ISIS-Upd: from SNPA c201.22dc.0000 (FastEthernet0/0) %CLNS-4-AUTH_FAIL: ISIS: LSP authentication failed So there you have the system ID which was 000.0000.0002 for my NET which was 49.0001.0000.0000.0002 This URL seems to explain it pretty well: http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a0080093f36.shtml#tshoot [3] Best regards, Daniel Dib CCIE #37149 2013-07-01 19:33 skrev [email protected]: > When testing on 12.4 code I get the following from debug isis > adj-packets and debug isis authentication information: > > ISIS-Adj: Rec > L2 IIH from c201.0d84.0000 (FastEthernet0/0), cir type L1L2, cir id > 0000.0000.0002.01, length 1497 > ISIS-AuthInfo: Packet failed the md5 > check, 1497 bytes, type 16 > ISIS-Adj: Authentication failed > > So the MAC > address and interface is recorded.

I have found some debugsthat confirm that we're having an authentication problem but they alsodon't show the source of the problem. Not even an interface.
