i think this is somewhat related busy naps and overloaded interconnects and i'm wondering if anyone else has noticed this kind of thing. i've noticed in debugging on my border router at mae west (the only place i actually looked at this) there is a lot of broadcast traffic that shouldn't even be propogated at a nap, such as: Sep 5 09:07:02.424: UDP: rcvd src=205.137.63.52(513), dst=255.255.255.255(513), length=68^M Sep 5 09:07:02.424: UDP: rcvd src=205.137.63.52(513), dst=255.255.255.255(513), length=68^M this is a unix box i'm guessing trying to get information via whod on the fddi ring at mae west. i've logged a large number of these broadcasts this evening, all within milliseconds of each other. seems to me we (collectively) don't want/need to see this type of traffic floating around when we're trying to push real customer traffic through the interconnects. or how about broadcasting bootp/tftp requests across the ring? i've logged an equally large number of these tonight: Sep 5 09:06:12.735: UDP: rcvd src=0.0.0.0(68), dst=255.255.255.255(67 ), length= 308^M Sep 5 09:06:12.735: BOOTP: opcode 1 from host 0.0.0.0 on Fddi10/0, 64508 secs, and even better: Sep 5 09:20:16.714: UDP: rcvd src=163.179.51.7(65044),dst=255.255.255 .255(69), length=29 is someone trying to pull a config (any config) via tftp from whomever happens to have one? this kind of traffic just seems very wasteful and unneeded at the naps. i can't see that this is even useful to the folks doing it. more traffic clogging up the pipes. -brett - - - - - - - - - - - - - - - - -
