ICMP Errors in response to multicast

[Bill Fenner <]

Folks,

  I did some brief monitoring of the Infocom MBone session, and it appeared
that the sending machine was getting completely hammered by ICMP's - I saw
several different sources of ICMP errors.  All of the culprits that I was
able to SNMP were running IOS 11.2(9); this is a known bug (CSCdj43447)
fixed in 11.1(15.4),11.2(9.1),11.3(0.7).  Please upgrade your router if
you're running anything earlier.

  There are also some ICMP-error sources that do not appear to be Ciscos.
If you are responsible for one of these, please work with your OS vendor
to resolve this problem.

  Bill
