Just one, and I plug in like a string of three power
strips, and I plug nine devices in there, three
routers and six switches or something. Yeah, that's
probably going to draw so much power from that one
outlet it's going to trip my circuit breaker. So that's
one of our goals here, is prevent that. How do we
prevent that from happening? So step number 1, if you
can, ideally power your devices from more than one
circuit breaker. This can be kind of hard to do, because
in most peoples homes and apartments, all the
electrical outlets within a single room usually feedback
to a single circuit breaker. But if you're one of the
lucky people where that's not the case, where the
outlet on this wall and the outlet on this wall lead to
two different circuit breakers, fantastic. Plug in
a power strip that feeds three of your routers
powered by this one, another three routers powered by
this one, so try divide it up. Or if your spouse
doesn't mind, run a long extension cable out of your
office into the living room, or into the bathroom, or
something. But the idea is to try to divvy up the load
among more than a single circuit breaker. You should
know in advance how much power is each one of your
routers and switches going to draw, and this is where
you're going to need to dig into the datasheets of that
to find out. And then, and I will not take credit for
this. I actually got this from this Tech Republic
website right here. This is a nifty formula that someone
came up with that says based on your circuit - at least
in the United States. I can't speak to people in
other parts of the world, but at least in the United
States, most of our circuit breakers in our house are
20-amp circuits, and they feed with 120 volts. So here
in the U.S. if you follow this formula, you can see
right here it basically says at the bottom, Okay, so for
that single circuit breaker, it will handle a maximum of
1920 watts. Now you look at your data sheets and you
say, okay, well if I got 6 routers and 4 switches on
this one circuit breaker, will that exceed this? Also,
keep in mind also that many times in your house circuit
breakers are powering other things. It can be very
irritating if you're running your lab and all of a sudden
somebody goes in the kitchen, turns on the
microwave, and boop, all the lights go out, because now,
that just exceeded your wattage. This is also
something people that sometimes don't think about
is not only do I have enough power in these one, or two,
or three outlets, but the circuit breaker that's
feeding those outlets, what else is it powering? Is it
powering my washing machine and my dryer? Is it powering
my microwave? You got to think about these things as
well. When you're done with the planning stage, what's
the end result of this? The end result is, you've come
up now with a variety of drawings, a variety of
network topologies that will support your various
features. You've got in front of you 10, 12, 15
pages of various router and switch drawings that maybe
you can collapse all into one diagram. You can say,
okay, based on all this, I've now determined that
with four routers and two switches, I can do
everything I need to do. That's the end result of
plan, is you've got one final drawing topology
diagram. So you've got a thorough understanding of
how many chassis you're going to need, how many
routers, how many switches, how many interfaces you're
going to need. You know, I'm going to need a total of six
fast Ethernet interfaces, I'm going to need a total of
four serial interfaces. You should know that by the time
you're done with this. You're going to know how
many extraneous devices you need. We haven't really
talked about that, but you're probably going to
want to also purchase things like hubs and laptops. So
you want to integrate a server, a real server, into
your rack, that's something you'll have to think about.
By the time you're done with this, you'll know that. How
many non-Cisco things am I going to need to incorporate
into this rack, hubs, PCs, servers, cables, things like
that? Lastly, by the time you're done with the plan
stage, you have confidence that your facility, which is
your home, will support the electrical requirements of
this rack that you planned to build. That's the end
result of the plan stage. Let me just take a quick
moment here to see what questions there are before I
continue on. So Carlo asked if this was going to be
uploaded to YouTube later on? Excuse me. I don't know
about that. For this particular session, probably
not. This session will probably only be
available on INE's streaming.ine.com website. I
don't think they plan on making this as one of the
free videos on YouTube. I could be wrong about that,
but I don't think so. Someone's asking about the
CCNP route workbook. That's just going to be completed
over time. My goal is, over the next six to nine months
I will continually add tasks to that here and there. I've
just added some OSPF tasks to it, I plan on adding more
OSPF. Over time I'll add BGP and service level agreements
and stuff like that. But, it's an ongoing work in
progress, so it's going to be a few months before
that's done. TSHOOT will also be the same thing. I do
plan on coming out with a TSHOOT workbook, but just
like the route workbook, when that first comes out it
will probably have somewhere between three to five tasks
where you troubleshoot a typology and then it will
build over time on top of that. Someone was asking do
we have a copy of the virtual software available
for the CCIE lab on INE's website? No, we don't.
That's not available on our website. Yes, this will be
available on demand. Actually, I was told by our
producer that it's probably only going to be about a
week, if that, before this is available. I previously
said like two to three weeks, apparently he thinks
he'll be able to get it out much quicker than that, so
there we go. Steve, you asked a good question. What
about end devices and traffic in the network for
testing? Yeah, exactly, so this is also one of the
things you want to think about during this plan stage
is what kind of traffic do I plan on creating to test
this? For example, let's think about routing
protocols. If you want to practice some complex route
filtering and route summarization you probably
want to have a minimum of 10 or more networks being
advertised from 1 router to the other. Well, how do you
get that to happen? Easiest way is probably just to
create a bunch of loopbacks. Or to read a bunch of static
routes and redistribute them. What about actual data
traffic? You know, Telnet traffic, where you can
always initiate the Telnet from a router. But what if
you want to have traffic flowing through your home
lab. Which is traffic that routers themselves and
switches can't really create, like email traffic.
Or, I don't know, web browsing traffic, or
something like that. Well, if that's your desire, then
you're going to have to think about, Okay, then I'm
probably going to have a minimum of 2 end devices
connected to my Rack. So maybe part of your budget
is, what's the cheapest laptop I can find? You know,
can I find a-- or maybe not even a laptop, right?
There's a lot of desktop PCs that people bought four/five
years ago that they're now selling on eBay for probably
25 or 50 bucks. You don't need a laptop to generate
e-mail traffic or whatever, buy a real cheap desktop PC
that's not even sold anymore someone selling for like
25 bucks, great usage of something you can connect to
your rack to generate traffic. There's also tools
you can download for free, a software where you can
download, where you can generate traffic for all
kinds of stuff. For example, I don't know if I have it
here on this laptop. Yes, I do so I'll put it over here.
So this here-- let me open it up. I don't use it a lot,
but this is called the Colasoft Packet Builder. I
got this for free, don't have to pay anything. Let me
just move it over a little bit, but this is an awesome
tool. You can use this to build streams of traffic and
you've got full control over your streams of traffic. You
can generate-- you can tell it how fast you want that
traffic to go and Bits per second or Bytes per second.
You can tell it what type of traffic do I want ARP's
DHCP. You can even get into individual fields and tweak
like the hexadecimal of individual fields, all for
free. So this is a great thing to install in your
laptop and now turn your laptop into a traffic
generator, so going to want to think about that as well,
yes. So do I need actual physical devices? And if so,
how many of them which I'm going to connect to my
network and pump traffic through it? That's going
to be something you're going to want to come up with
at the end of this Plan stage right here.
