Can you tell me more about your 3550 macros scripts maybe an example

Hi Ryan,
Here's my suggestion to you - use the labs vendors to prepare yourself
for the exam - not to simulate the exam. I personally use the IEWB
from Internetworkexpert and have seen labs where loopback and
connected interfaces are left unadvertised. If you really want to
simulate the exam, go back and check if "...full connectivity" is
required and make it work if so - advertise connected interfaces while
making sure you're not loosing some routes and breaking something
else. Usually what i do is to reload all routers after I finish the
IGP section and run my tcl/3550 macros scripts to check that
everything is fine - notice that at this stage you still might not be
able to have full connectivity - for example the lab might include BGP
as means to reach some parts of the network, I've seen labs where
later on a task says that 0/0 should be originated somewhere, etc. So
the conclusion is that you need to be flexible with your tcl scripts -
at IGP sections you might be checking a subset of the whole
connecitivity and latetr on after BGP section you should be able to
re-check everthing.
Again - my recommendation is to not worry about this aspect - what
everyone says about the real exam is that the task will be very
specific and clear so use the workbooks to find your weak spots as we
all can do redistribution of connected routes ;)
