If you had additional interfaces on the listed subnet then they would also

It is done because ISDN lines are considered two physical paths that are
bonded together using PPP multilink or Cisco's proprietary bonding.  If you
don't disable route caching then the tcp/ip conversation will always be
switched out the same physical path (your big download will only use 1/2 of
the 128k connection).  It's easy to test that...just remove it sometime.

no-fair queue appears to be the default for asynchronous interfaces on the
later versions of IOS.  To be honest, I'm not certain why FIFO offers better
performance than WFQ would on asynch lines; I can't find a good explanation
on CCO right now.

You'd have to be careful about advertising those routes back out to BGP

There should be quite a few, actually.  Most resellers are not interesting

I don't see why STP delay would be an issue; perhaps you are referring to
ethernet traffic?  With a Gig backbone my trunk utilization is under 2%.
There is only one blocked link (top floor to basement).  Regardless of
approach, there will be a 30 second delay if you use backbonefast.  

Separate VLANs per floor would be be nice but redesigning the network isn't
an option right now.  They just went from public IP's to a single /16

My biggest concern is the lack of redundancy in this design.  If the
basement switch goes out then the entire company is down.

I have a Cat 4006 or 5500 on each of the floors.  I utilize a daisy-chain
approach with Gig Ethernet over fiber.  This way if any one switch fails
it'll only take out one floor.  You'll want a lot of redundancy in your
server room switch because if it goes out, then once again, your entire
network is down.

That depends upon a lot of factors, but you know your situation the best.  I

The book that I read right after the CCNA was Caslow's Bridges, Routers, and

I think the key is to not use them as your sole reference point.  I failed

I'm not going to buy a COS switch.  A 2901 will set you back $1400 or so and
it still won't have ATM, FDDI, or an RSM.  It makes a lot more sense to get
access to a switch at work or rent some rack time; I decided to take the

If you just want to experiment with ISL routing, trunking, VLANS, and that

I haven't seen the NLI book, but their website is fairly impressive.  I'm
planning on buying their labs.  

I did the written a three years ago (I never got around to the lab) and the
study materials from ccprep were the closest to the real thing.  I bought
every CCIE book/online subscription available at the time (not much) and
they were the best; I'd imagine that they still are good.  Their white paper
on token-ring is invaluable.

Really?  I've never had a problem with it on anything important.  I've 
also worked with the author on a couple minor additions and he seems 
like a great guy.

Use a console cable on the nearest switch and telnet to the others.  The 
point is to avoid having to walk to every individual switch with a 
laptop.

This was a good discussion.  When I took my switching course, three 
years ago, they were quite adamant that trunking could not be done on a 
10 mb interface.  Of course, that was before dot1q was available on the 
routers.  If someone took their courses a while back then they probably 
aren't aware of the changes.

Your question is not clear.  The SC0 port isn't relevant if you are 
using trunking to connect two switches.  All you have to do is "SET 
TRUNK mod/port ON" on both switches and you are done.

If you are talking about routing between VLAN's then you need an RSM or 
a router that is capable of ISL routing (2621 or better).

Re: CCNP exams [7:39172]

I agree, in principle.  I easily passed Microsoft's 70-240 exam.  
Everyone was whining about how low the pass rate was and how difficult 
it is.  I had no problem with the new format and I didn't find the exam 
difficult after 6+ years of working with NT.

That really isn't the point, though.  The issue is that a certain 
percentage of computer people take the "it was easy for me so you must 
be a moron" approach to these topics.  Life just isn't that simple and 
just because you/I can pass an exam or wade through the B.S. doesn't 
make a vendor's approach the correct one.

I understand what you are saying, but your comments are simplistic.  There
are a lot of people out there with considerable experience and skill that
are not good test takers (a good friend of mine is one of them).  People
that are not native English speakers can also have problems with these
exams.

Many of the certification exams test your ability to memorize command syntax
(that in real life you'd use the "?" for), have trick questions, or flat out
have poor wording.  To think that these exams are an accurate reflection of
ability is tough to believe.

MRTG is a freeware perl script that was written to gather router/switch
interface statistics using SNMP.  It creates attractive graphs and many of
us use it to do long-term monitoring/graphing of their connections.  You can
get more information at www.mrtg.org.

Of course, you could just do a SHOW INTERFACE command on the serial port and
add the two data rates togetherif you just want to check once.
