FWIW, you don't need bufferbloat for this to fail. A classic thing with switches (typically underbuffered rather than overbuffered!) is that when you run the links full, the OSPF packets get dropped and eventually your link flaps because the other side thinks you're down. This is one of the reasons why most L3 switches (well, anything that's advanced enough to do OSPF or the likes in the first place :-) ) have QoS at all: You need to protect your administrative traffic. /* Steinar */ -- Homepage: http://www.sesse.net/ _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
