Let me share my thinking on the CertificationZone BGP series that I'm writing.
To a significant extent, I'm recreating my own learning experience
with Internet routing. As you suggest, Francisco, that is much more
than BGP.
Personally, I found BGP proper very hard to understand until I
focused on what problems it was intended to solve, rather than the
details of the protocol. Great lights dawned for me when I dug into
routing policy documents, first RIPE-181 and now several RFCs and
tutorials on Routing Policy Specification Language (RPSL). NANOG and
IETF work also helped a great deal.
I haven't seen the new Cisco courseware. ACRC, at least 11.2 where I
was involved in development, was awful on BGP. It had a lot of
hand-waving, and the labs had NOTHING to do with real-world
requirements.
My sense is that the CCIE lab tests on some rather unrealistic
configurations, due to limits of time and number of routers. Unless
you have a BGP traffic generator like BGPSIM, you are simply not
going to see significantly long AS paths with 5-6 routers. You'll
need at least 4-5 routers to see something like hierarchical route
reflection.
So, in the CCIE-related BGP papers I'm writing, I try to deal with
the big picture, the problem that routing is trying to solve, and
then focus on specific configuration.
