To all CCIE R&S Students,

Garry Baker, Steven B and I were talking about the TSHOOT class/TEST from
the new CCNP track, and this is what i was saying, see if you agree:

I've been teaching/consulting for a long time, and believe it or not base
knowledge is where most of the CCIE students lack. Just to give you an
example of what i am talking about:

Let's say we have three routers sharing an Ethernet segment, using the
following IP addressing:

R1's F0/0 - 10.1.1.1 /24, R2's F0/0 - 10.1.1.2 /24, and R3's F0/0 - 10.1.1.3
/24 and all three routers are in VLAN 100.
These routers are running RIPv2 (comparatively a simple Routing protocol).
R2 and R3 are injecting a default route using "default-information
originate"

This simple task wants R1 to see two different default routes, one coming
from R2 and the second one coming from R3.
If you lab this very simple scenario, you will quickly see that R1 ONLY gets
a single default route, the question is WHY?

A question like this should ONLY take a student, a totally ready student
less than 5 minutes to resolve, but since the basic knowledge is lacking or
it's NOT up to par, it may take up to 15 minutes. What if the task states
that you should resolve this in three or four different ways? What are those
three or four different ways, the problem is that SOME won't even recognise
the problem, whereas, others will continually ping and do a "Show run"
command.

Let's see how long this simple scenario takes you to resolve. Unicast me the
solution, i need three to four different ways to resolve this, two of the
four should be done in layer 2, and the other 2 in layer 3. Hey......as far
as the difficulty level, i rank this 1 or 2 out of 10.
