Good reference for Troubleshooting speed tips?
Does anyone have any good references they could share for increasing your speed in Troubleshooting? Mainly looking for references on strategies.
I watched all of the INE's VoD series for Troubleshooting v5 with Dave Smith, and he offers great strategies/tools in how to pick up key clues if something is wrong.
E.g., start trace; all *** means no route on device, if have a few hops then ***, means most likely return path problem (except if MPLS). Divide and conquer vs Top to bottom or bottom to top, etc.
Anyone have any pointers? This to me is the trickiest part of the lab, being able to narrow down problems quickly/efficiently in the TS section. I would love more hands on/broken labs, but Ive been through INE's troubleshooting labs multiple times.
