I'm sorry to confuse you I thought there are more ALG routers On ORA you can see that ALG originated and advertised 3 LSPs
I see you mentioned some LSPs are not being propagated I'm thinking maybe some area discrepancy in the net id Please note the 49.xxxx or 47.xxxx should be the same on all routers in the layer-1 domain Also it might be some routers along the path are layer-1-2 some are only layer-1 or only layer-2 and that's where some of the LSPs might get lost adam From: Vincent De Keyzer [mailto:[email protected]] Sent: Monday, January 14, 2013 11:31 AM To: Adam Vitkovsky Cc: [email protected] Subject: Re: [c-nsp] CLNS/IS-IS routes Hi Adam, thanks for the quick answer. About the "ES" role of the server: Alcatel confirmed that their servers indeed need to be configured as ISes (which I agree sounds strange). By "each of the Algiers", you mean that I should see "rtrnal01" more than once in the list below, like "rtrmar01" and "rtralg01" do?

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.
