My mail server is spitting the dummy (I am NOT having a good week so far), so excuse me if this appears twice.
Cisco has admitted that yes, there is a bug with IPX in 12.1. They suggested that we upgrade to a scarily recent version of IOS - we will back out to 11.2 and test the new version first rather than bunging it straight into a production core router! In response to Priscilla's suggestions - yes, we did check the update interval. Just for fun we explicitly set it (to 59 seconds instead of the default 60), but that made no difference. Turning on debug ipx on these routers would crash them, but we did check that last week when a similar problem showed up in a test lab. debug ipx rip act showed one router sending the (correct) updates, but the other router giving no indication that it was seeing them - no errors, and no debug output. Oh, and if anyone has anything interesting to say about tuning the frame-relay broadcast-queue command, I'd love to hear your thoughts :-) (I told you I was having a bad week...)

So I would say it is on topic! ;-) Please let us know what you find out. It sounds like a bug... Have you made sure nobody configured this command on the interface (or that the new version didn't default to it?) Router(config-if)#ipx update interval {rip | sap} {value | changes-only} Can you turn on debug ipx routing or would that be too risky on your network?
