Hello. Welcome back to I see new one interconnecting Cisco networking devices part one this episode 3 to 3 trucking protocols and sending data between billions. I am Trenton Heroin are very structure for this course.
Last video went over the V Lane and Shrunken Concepts is absolutely recovering the to Truckee protocols and how you send data between two different villains.
Like I said, we're gonna talk about the i s l tracking protocol. And then we're gonna talk about the 802 that one Q trunk protocol and how you four data between the villains
and quick pre assessment here, Which of the following 1,000,000,000 I d. S are considered to be in the normal range.
Give me a few seconds.
Here it is. 10 501,000.
We'll see here in a minute What the normal ranges are.
So I s O is the inner switch link.
This is a Cisco proprietary trunk of protocol so that those actually adds the veal intact to the front of the frame header.
Um, it will encapsulate that Internet frame into an I S l frame when it sends it over that trunk report trunk link. So a lot of the newer models of switches actually don't support it because there's slowly starting phase out with the 802.1 Q,
which is the IEEE standard is so it's open standard that everyone used. So if you have multiple different equipment,
it's the one that everyone's use it. Um,
so they all have a 12 bits villain i D. Which leaves you for
But the villain zero on view in 40 95 or reserve so leaves you with 4094 villains in reality.
So the a toe to toe one cute. This is the IEEE Open standard. It has multi vendor support.
So what it does is as the vigilante into the original header,
so it doesnt encapsulate it like I s l did.
But when you need to on the switch, you're gonna define one V lane to be native. So the default on all switches is Cisco switches is villian one.
It's a very good idea. Change that or to put unused ports to
be land 4094. You know, something like that,
Um, because you don't want them to be given for malicious activity go over that.
So it actually won't tag that native delaying traffic on the trunk like the
like, the demonstration we had in the last episode. It won't tag that native you, and it will just send the Internet frame right over it.
But both switches must have the same native DeLeon said otherwise is gonna assume, you know, if one as what set on the line one on ones on view a 10
it comes in on that one is gonna assume that this is traffic met for veal, and 10 is gonna get there is going in the wrong sub net. It's gonna say, you know, what the heck did I do with this frame?
So again, it's a 12. It villian 04 95 reserve leaves you with 4094.
So one through 1000 and five are considered be the normal range in 1006 to 4094. Because where doesn't it? Finding is reserved Are considered the extended range.
So we look at forging
between different violence. We have a few different options here. So, like we had before later, two switches can't route traffic between two different re lands because
you think about a land there. Think about what's on the broadcast domain.
They're gonna be on different subjects, right? They can't be on the same sub net if you're on the same V land her different relays.
So the easiest way to do it is to use your layer two switches with a router or what's also known as a router on a stick. Because you have all your devices down with the one link that goes the router,
So you can have each viewing on a separate link. We we did with the switch, but that will consume your router ports extremely fast.
Or you can set it up with the trunk link, which is what you generally you're gonna d'oh!
Or you can use a layer three switch, which is, or a multilayer switch, which is going to alleviate the load on all the upstream routers
because as of right now,
wants to send a message down to this guy down here. He can't just go through. The switch is they're going to hear it's gonna tag that header.
There's gonna tag the frame and then come back down and then go down here.
Remember that trunk link so you can see it all just goes through one like, now And just, you know, instead of consuming up 10 ports on the route and were only consuming one.
And here's what it would look like with the
So it's simple. Is this because it has a layer to switching and way or three routing? Don't come in.
Okay, I need to go down on him.
So we move on to the post assessment here. Which of these is Thesis Co proprietary trucking protocol.
All right. It is tthe e i s l inter switch link.
In the next episode, we're gonna look at TV land configuration and verification. So we will break out the lab equipment for this one. So if you want to get a paired default, could fig it all ready to go?
you have any questions? Needs help. Feel free to shoot me a message.
Thank you for washing this lesson for a scene in exports
