All language subtitles for 3. Packet Tracer Campus Network Part 3 Answers Part 2 HSRP Part 2

So that was the configuration for v land 10.

That means that for the P.C. and V land 10 we can configure the P.C. to use a default gateway of that

H.S. IP router.

The IP address that we need to configure the PCI as is shown in the output here tendered Wanda.

Tender 10.

So tender 1 10 top 10 slash 24 subnet mask Sol open up a command prompt

IP config that's the IP address of the piece he cannot ping its default gateway yes it can now notice

the OP cache.

Notice the MAC address used here for the default gateway is the H.S. IP router.

In other words the virtual MAC address as we can see over here so once we've got our network configured

we should be able to ping devices in other villains so let's complete the configuration of ages opium

both these core routers and then configure default gateways on other devices and test connectivity so

configuration on VLAN 10 is as follows On VLAN 20.

This device is not the spending tree root so we want code to to be the ages IP Act active writer for

VLAN 20 because it's the root

so all we'll do here is use the command stand by IP tendered one to twenty to five 4.

Now before I configure switch to I want this device to become the active router.

So we need to give it some time and then I'll show you what happens when the other device comes on line

with a higher priority and pre-emption switch too will become the act of rudder once we can figure it.

But notice now that core 1 is active.

So if I type show Stand by

for VLAN 20 the local router is the active router because the standby rota is not known virtual IP addresses

this.

Notice the virtual MAC address is the same MAC address.

But that's not a problem because these devices are in different v lands so they don't see each other's

traffic.

So devices in one VLAN won't be confused with sending traffic to the wrong device in another VLAN because

of V lands separate MAC addresses

so on this switch interface VLAN 20 stand by one IP address is gonna be tendered one to twenty two five

four.

But now what I'm gonna do is I'm going to force this device to have a higher priority and I'm going

to force preemption so that it becomes the active Roorda.

Notice as soon as I did that it became active I'll show you in a moment what happens if we don't use

preemption.

So show standby.

Shows us that the local switch is the active Roorda virtual IP addresses this local Rada is active standby

rowdies.

UNKNOWN But let's check again.

There you go.

Stand by Roorda is call 1 and what you'll notice on core one is that the state changed to to stand by

so show stand by again for veal and 20 shows us that this Roorda is no longer the active Roorda.

It is the stand by Roorda Roorda 2 or CO 2 has become the active Roorda and we can see something similar

on the side.

OK so that's veal and 20 shows spanning tree veal 30 core one is the root for veal and 30.

So we want to call one to become the H.S. or be active but let me show you what happens.

Firstly if you don't configure preemption so I'll specify on code to that for VLAN 30 the standby Rory's

tendered wandered thirty two to five four.

That's all I'll configure.

Once again

for V Line 10 and veal and 30.

We don't want the writer to be the active Roorda.

So all I've configured is this command stand by one an IP address now on call 1 interface of Eylandt

30 standby 1 IP tendered one not 30 to 2 5 4 standby.

1 priority 200.

So I'm going to change the priority but not configured preemption.

So notice the difference.

Show run shows us the output on villain 10 it's configured with preemption on V land 30 it's not configured

with preemption.

And notice it became a standby device.

This device is already the active device.

So without preemption if a device is already the active device or active Roorda the other device is

not going to force itself to become the active Roorda.

So show stand by again local Roorda is the active Roorda.

Just need to give it some time to sort itself out.

On this side it's going to stand by

so core one has learnt that Coty is the active Roorda and the local device is the stand by Roorda on

this side that should hopefully sort itself out.

That might be a packet tracer issue but notice the local Roorda is the active Roorda we still see Stand

by Roorda as unknown.

The point is is that this device even though it's got a higher priority has not become active and that's

not what we want.

We want a type of standby one preempt so that we force core one to become active and notice now that

I've done that it's become the act of Roorda.

So show standby shows us that pre-emption is enabled and it's become the active Roorda and court to

is now the stand by Roorda and we can see that in the output here.

So show Stand by we can see that to the active Roorda is call 1 local Roorda or local switch is the

standby Roorda.

So don't forget to specify both a property and preemption.

Now what about for V Line 100 shows spanning tree and let's do that for vlan 100.

In this example we made the switch to the route for veal and one hundred.

Now it may have been better to make such one the route for veal and 100 but I simply wanted to load

the villains across the links and we have configured ether channel here.

So it will improve performance but that means we need to configure core to as the HSR AP active rota.
