CCIEv5 First Attempt Fail - Brussels
So my first attempt was a fail =(. I kind of expected it, I wasn't an expert on everything BGP, MPLS and Multicast.
Definitely wouldn't be afraid of the Diag section, I actually quite liked it.
Scale is huge, both on troubleshooting and configuration. I was a little stunned on the scale of the configuration section and definitely wasn't prepared for the level of interdependence on tasks. Remember that if you don't have reachability, even if the configuration is correct the tests will fail and you won't get the points.
