Here I have the problem again. One neighbor state remains in state "loading". I activated some debug messages.

As you can see, the sequence numbers don't match. Is that the problem?
These messages are useful to locate the problem. The problem is not really a sequence number mismatch (this might happen and it is OK), but some subtle bugs in premature aging of LSAs (which happen if router receives an LSA created by its previous instance before restart). I found these bugs several weeks ago but i didn't know that they may cause such problems. I hope i will fix these bugs soon. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
