I have run into plenty of problems caused by MD5-related bugs. 6500/7600 can still figure the MSS incorrectly when using it. It used to be possible for that particular box to send over-sized frames out Ethernet ports with MD5 enabled, which of course were likely to be dropped by the neighboring router or switching equipment (perhaps even carrier Ethernet equipment.) Obviously that can be a chore to troubleshoot. Sometimes we choose to use it. Sometimes we don't. -- Jeff S Wheeler <j...@inconcepts.biz> Sr Network Operator / Innovative Network Concepts
