- If my questions are naive, I apologize, but I am fairly new to the
- science of networking.
-
- We recently experienced a failure of our Cisco router due to the following
- scenario:
-
- One of our workstations, running IBM TCP/IP for OS/2, was improperly
- configured. The file that controls the IP address and the default routing
- was typo'ed such that the machine was accidentally assigned the same IP address
- as the Cisco router. This brought down a major part of our network as the
- Cisco stopped routing. Several hours were spent finding the problem.
-
- First of all, what troubleshooting techniques would have led our team to
- discover the exact nature of the problem more quickly?
-
- Secondly, is there any way to protect against this sort of thing?
-
