Thanks, Chuck, and I'm really not trying to divert the thread too
much off topic. From my personal experience, the light didn't dawn
for me on BGP until I started studying routing policy (RPSL, the
routing arbiter), etc., and finally figured out the _purpose_ of most
of those knobs.
Even more than DLSW, in CID, IBM protocols were always a joke, at
least from my standpoint as having been an NCP/VTAM system
programmer. There is so much to know on the IBM side that I couldn't
see just studying the Cisco part being terribly useful.
I'm still a believer in narrowing the scope and deepening the depth
of the CCIE, using an awfully strange model -- the team specialties
in the TAC. Even if that's not done, knowing the context and
motivation of why certain protocols were developed, I think, makes it
much easier to understand what they are doing. Knowing something
about queueing theory, at a not terribly mathematical level, gives a
lot of insight into QoS and performance. At least scanning through a
computer science textbook about memory management and interrupt
handling helps a great deal with switching paths, although the Inside
IOS Architecture is superb.
