>But Oran does not seem receive from Algiers any of its 6 CLNS neighbors (and that includes the server): I'd check the ISIS database on Oran to see whether it received an LSP from each of the Algiers. Than you can check for the verbose output to see whether the particular LSP contains all interfaces.
Also you mentioned servers -shouldn't those run ES-IS with the routers? adam -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Vincent De Keyzer Sent: Monday, January 14, 2013 9:32 AM To: [email protected] Subject: [c-nsp] CLNS/IS-IS routes Hello all, We are currently troubleshooting an old, badly-documented, non-supported, CLNS/IS-IS network (for management of Alcatel NEs). One of the issues we have identified is IS-IS routes not being announced by one router to another (this might or might not explain the overall problem of no connectivity, but let's go step by step). The two routers are ALGiers and ORAn, directly connected with a serial E1 link. The adjacency looks good to me. Algiers correctly sees Oran (and has a CLNS neighborship with the server we are interested in): ALG2-R26-01#sh clns ne System Id Interface SNPA State Holdtime Type Protocol 0007.729E.FFEE Et0/1 0007.729e.ffee Up 92 L1 IS-IS 0007.72A2.FEA6 Et0/1 0007.72a2.fea6 Up 91 L1 IS-IS 0020.602B.CBB4 Et0/1 0020.602b.cbb4 Up 95 L1 IS-IS 0020.6013.2DD2 Et0/1 0020.604a.972e Up 92 L1 IS-IS --> 0030.6E4B.455C Et0/1 0011.85c7.3ec0 Up 97 L1 IS-IS <----- Server 0030.6E4B.47DB Et0/1 0012.799d.51a6 Up 95 L1 IS-IS rtrnoc01 Et0/1 0014.1ce6.60fd Up 9 L1L2 IS-IS rtrann01 Se0/2 *PPP* Up 24 L1L2 IS-IS --> rtrora01 Se0/3 *PPP* Up 26 L1L2 IS-IS <----- Oran router 1880.F524.8FF0 Et0/1 1880.f52d.958e Init 48 L1 IS-IS ALG2-R26-01# Oran sees Algiers: ORA1-R26-01#sh clns ne System Id Interface SNPA State Holdtime Type Protocol 0020.6013.37F2 Fa0/1 0020.6013.37f2 Up 96 L1 IS-IS --> rtrnal01 Se0/1/1:0 *PPP* Up 24 L1L2 IS-IS <----- Algiers router rtralg01 Se0/1/0:0 *PPP* Up 28 L1L2 IS-IS 0020.602B.CF8A Fa0/1 0020.602b.cf8a Up 46 L1 IS-IS 0080.9F20.0931 Fa0/1 0080.9f20.03a3 Up 93 L1 IS-IS ORA1-R26-01# But Oran does not seem receive from Algiers any of its 6 CLNS neighbors (and that includes the server): ORA1-R26-01#sh isis route | i 455C ORA1-R26-01# (You might have noticed that the CLNS names are not consistent with the hostnames, but CDP does confirm the situation ALG2-R26-01#sh cdp ne Device ID Local Intrfce Holdtme Capability Platform Port ID ORA1-R26-01 Ser 0/3 163 R S I Cisco 2801Ser 0/1/1:0 (...) ) All seven routers in the network have already been rebooted. Any idea why this inconsistency, or on how to troubleshoot further?
