How to become a Learning Partner (that’s something your business does) or how to become a CCSI (trainer - that’s something an individual does)?
They are two entirely different things.

Uhh…DHCP? Seriously, why would everything be static? I haven’t seen that in years…

What I was thinking of though, is the exact output of debug command. Is it really EXP or CoS? Because since you are […]

I think i’m addicted to GS, since in those 6 or so hours that it was down, i started to get real nervous and basically display all symptoms of addiction. Nervous walking from side to side, checking my email every 2 minutes even though I know it’s going to be updated automatically, searching through archives…
But […]

Hello,
I just tried a very similar scenario to yours (Uniform mode) with dynamips.
If I turned on “debug mpls packet”on P1 (where the match and rewrite of the EXP occurs) then the policy maps/service policies wouldn’t work. It confused me because I had seen some increment in the counters but that was from the time […]
