a little Welcome back to cyber is create a sudden it.
Today we're gonna go over super netting and I will be an instructor. Trenton Darryl. So let's go ahead and get started here.
So you said were today Were you over super netting? And what that is
the computer networking note that Com says super netting is the practice process of summarizing a bunch of contiguous subject and networks back into a single large network. Super netting is also known as route summaries, ation and route aggregation.
So some more ization. What that essentially is doing is combining multiple networks routes into one. So what does does is it makes for a smaller and routing table. It makes it a little bit easier to read because you're not searching through, ah 100 different sub nets, right?
You are just searching for you know, you can see that. Okay, here's the slash 20 that I need to get to write. You know that your network is in that slash 20 right?
So makes it a little bit easier to read when you're not searching through 100 different routes. So it is the process of taking some by continuous if you don't. It is. It means, uh,
especially consecutive. Right? It is networks that are
right in the order of each other, right? You don't. You know you're not missing ah, slash 24 block right in the middle of it. But it's networks that are right in line that you can push on to
a essentially a smaller, utilizing less submit bids
to push this. Right.
So So you have a bunch of slash 20 fours. You can
summarize this into a slash 22 or size 20 or something like that, depending on how many networks he have,
instead of having eight different networks and know that you're routing table.
It's really a simple is. That s so I'm gonna go ahead and move on here. We're gonna do a quick
So what we're gonna do,
I'm gonna draw out couple networks here.
So say we have Harry's hair cut emporium
and this is broken up into four different blocks, right?
26 a slash 26 in its last 25. So
I am gonna do this, right?
right? So right now we would have three different networks coming out of this routing table. Right?
Imagine we have router one.
We had 23 and four, right? Say too.
Three and four. All right, so we have their different networks, right?
is you know, I s r right?
Was he was run over here. So instead of pushing three different networks over to this guy, we can summarize this in to this right here, Actually, because we own this whole slash 24. Right now, we can just update it. We can send the route to I S r. A router here that we could say,
Hey, in order to get to this 1 91 6810 slash 24 network
Go to go through me right here. You go through this point, and then I can figure out where to send the rest of it. Right? So this guy only has, you know,
suddenly her one routes in his, you know, network, right?
So last 24 instead of having to slash 26 its last 26 25
anyway, So Okay, three routes isn't that bad. You know why? Why would I use this? But if you're looking at like, let's say a Class B network, right? The more you can summarize that Class B, when you're talking about, you know, quite a few different
the more you can condense that routing table, the better. It's better on the actual switches. It better on your network engineers. When you're looking into stuff
somewhere, you can do it the better.
And really, that is as simple as submitting it. So I'm gonna give you a quick quiz here and see if you can figure out what the super not addressing me for these three different subjects. Right,
Get a few seconds deposit, get a pen and paper out
already. I'm gonna get break out the pen and let's figure this out here.
So I didn t department, uh, school and began.
And that is on a slash 24.
He's gonna do in our slash 24 that one. That 104
and do wildlife is gonna do 1 to 0, and it's on a slash 23. So we're gonna go all the way through that one.
That's our total i p space.
So the total I p space that we're currently using 10 100
through 10 13 to 35 right?
So if you think about it, we're using
four Class C networks, right? So we do to 56
minus four. That leaves us with a sudden that mask of 2 52
So if we want to, we can add up the
sudden that's for the sudden. It best for this until we got 22 52
or what we can Dio is do a 2 55
minus 2 52 which gives us three
and the only way to get three.
There is one and one right. It was equal three and binary,
so that leaves us six sub net bits, right?
It's a network, said that host.
And here you are 16. We are using to for the host extra.
and that would leave us six bits for the sub nets,
16 nights, would be a 22
so it would be answered. D.
So the guys that hopefully
you did that's good if you didn't feel free to go back to the videos and if you really lost, feel free to shoot me, messaging, Try and help you out a little bit trying. Maybe explain so these concepts a little bit better.
Otherwise, we're gonna go ahead and move on to the lesson summary here. So today we just went over the kind of practice we went over how to do a little bit of super netting. Hopefully enjoyed the video today. But otherwise you look for to seeing you in the next one. Thank you.
