No reason to be sorry! I'm all for "vigorous" discussion ;-)
No BGP in the NA because we are talking about SMALL to medium business.
Yes, they should know about how to connect up to the Internet, using a
default route, etc. But you are not going to find that many ISPs, if any,
that are willing to setup a BGP peer with a store-front business with a 16
address space public network (or even granted they are given a /24 public
subnet). If you find any, let me know!
That's why I say EGP for NP. A medium to large business certainly may need
EGP expertise.
And I suppose that's a slight difference in the way people think about the
different certification levels. When I say RIP, IGRP, EIGRP, OSPF should be
requirements for a NA I mean the candidates should be }experts{ in those
protocols. Not just having a passing understanding, have read about it in a
book once, or used some study guide to rote-memorize answers to common
questions.
So, on the one hand I think the standards should be tougher, requiring
"expert" level knowledge for the IGP's, and on the other I don't think a NA
needs to know anything about EGP's.

And one last point, No LAN is an island, why two IG(P) protocols and no
EG(P) protocol?
A NA should at least a some understanding of how to connect to the
outside world - when to use BGP and when not to.
Sorry Fred, not having a go at you personally, but these are points we
all need to think about.

Oh, and while I'm on the subject - why EIGRP? This is a proprietary
Cisco Protocol. OK, I believe that Juniper may have implemented it, but
to the best of my knowledge no one else has.

I guess my expectation and Cisco's, or at least their current
expectations as listed on their web site, don't match then. By my
definition a beginner should know about CIDR, EIGRP, and OSPF. It's not
like they are inherently difficult to understand. People tend to make
it sound like rocket science or voodoo magic. It's just a routing
protocol folks.

with all due respect, I disagree. CCNA is promoted by Cisco as being
someone capable of designing and configuring a small network.
http://www.cisco.com/en/US/learning/le3/le2/le0/le9/learning_certificati
on_t
ype_home.html
"The CCNA certification (Cisco Certified Network Associate) indicates a
foundation in and apprentice knowledge of networking. CCNA certified
professionals can install, configure, and operate LAN, WAN, and dial
access services for small networks (100 nodes or fewer), including but
not limited to use of these protocols: IP, IGRP, Serial, Frame Relay, IP
RIP, VLANs, RIP, Ethernet, Access Lists."
my experience has been that small nets have less if any need for CIDR
knowledge or expertise.
Cisco has over the past couple of years been slowly upping the ante, and
I wish Cisco would get clear as to what skill sets are appropriate at
what certification level. Cisco tends to be all over the map on this,
and has been the netire time I have been playing at certification. But
in general, I believe the idea is that CCxA is beginner, CCxP is
intermediate, and CCIE is high level.
as with all things certification related, YMMV. I've known CCNA's who
manage large networks, and I've known CCIE's whose knowledge of certain
specific areas was less than expert. As can be expected, depending on
experience, job, place of employment, years in the field, etc.
