That's why I suggested weight or local-pref tweaks rather than accept nothing. That way you still spot if there's anything still going out via that leg (e.g. de-aggs or routes missing from other feeds) prior to downing the session. You're welcome to follow the less effort route - I'm just saying that *once* this saved my bacon, and it might again one day. -- Ian Dickinson Senior Network Development Engineer Pipex Communications [EMAIL PROTECTED] INOC-DBA: 5413*426 http://www.pipex.net _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
