A broadcast storm occurs when routers on a network accept indentification packets form other routers when they either

a. come online
b. have new information on there router tables
c. programmed to send out indentification packets at various intervals.

Broadcast storm happen to Bridges which are hubs that route ip addresses from one network segement to another.

The symptoms are a slow down of your network to the point where it is funcitionally unusable characterized by the constant processess of packets through your bridge with the constant flash of the light packet indicators on your repeaters.

To correct this problem you have to disable the bridge's ability to accept broadcasts. It is probably a software switch that you will have to configure on your bridge. This could disable some of the bridges capabilities. You may want to upgrade to a bridge that is more fully featured if this is the case.


hope this is a help to you

Are there situations when this happens in a network with hubs only that transmit IPX traffic?

Commented:
TCP/IP is involved because broadcast storms generally involve Wide Area Networks and hense Inter/Intranet.

If you are experiencing this problem with IPX you may want turn off bridging on your bridge to see what the effect is. You may want to look at your network segmentation. I know of several companies that were sharing one network which caused broadcast stroming, however that was with tcp/ip as well. This effect with IPX is unusual.
