I doubt many people have ever encountered the problem. The problem is rogue or misconfigured ISIS speaker with duplicate address. This ISIS speaker can re-advertise every LSP with superior SEQ or even MAX_SEQ. Outcome of rogue ISIS speaker advertising MAX_SEQ is that you need to first remove the rogue speaker and then reload whole network simultaneously or renumber every ISIS speaker. If you reload all network except one, whole network will relearn the bad information from the remaining speaker once it comes up. In this failure mode this feature would help to find the rogue ISIS speaker, so looks sensible feature to me, even when very partial support it will limit limit the domain where the suspect exists. I've personally not used it, and very much hope I'll never have need for it. -- ++ytti _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
